Step 2<\/strong> – Determine where to start: Can you see an error message or is the problem more vague?<\/p>\n Jump to quick answers to the following common errors:<\/p>\n OR<\/p>\n This message is caused by the theme you are trying to install having an incorrect file structure, the stylesheet actually being missing, or the theme not being a theme at all.<\/p>\n To solve it:<\/p>\n See this detailed guide for Themeforest themes<\/a><\/p>\n In most cases, this error is caused by a missing file, or an incorrect URL.<\/p>\n To solve it for post\/page links:<\/p>\n You can avoid 404 errors by periodically re-saving your permalinks, and making sure you never edit the slug of published posts, categories or tags. The Broken Link Checker and Redirection plugins can help if you really need to edit slugs and want to avoid broken link errors.<\/p>\n To solve it for images or other filetypes:<\/p>\n The most common cause of this error on new setups is an incorrect database path in the wp-config.php, but sometimes it can mean your database server is down.<\/p>\n To solve it:<\/p>\n Updates are a vital part of keeping your WordPress website functional, and sometimes they happen automatically. Whether you initiate an update yourself or are welcomed with a surprise maintenance message in your browser, wait a few minutes before taking action. You might just be trying to view your home page while an update is running on the back-end, in which case this message is totally normal. If the message doesn’t go away, or is keeping you from logging on, something has interrupted the update process, so you’ll need to delete the file yourself.<\/p>\n To solve it:<\/p>\n You’re installing a plugin, trying to load the customizer or clicking around in your admin panel just to have it time out and tell you you have insufficient memory or that your site memory allocation has been exceeded. This is referring to the amount of memory your database and scripts can use on your server. On most shared (cheap) hosting, the default memory allocated to WordPress is often not enough to handle setups with database-heavy plugins. These can include translation plugins, image management, gallery, link checking or SEO plugins. In many cases, you can increase the memory limit yourself.<\/p>\n You may also see the error worded as “out of memory.”<\/p>\n To solve it:<\/p>\n 1. First, try adding the following to your wp-config.php<\/a><\/p>\n This will increase the memory limit to 64MB (you can also set it to 128MB or 256MB if you want).<\/p>\n 2. When the first step is not enough, try deactivating all plugins except those that provide critical features to the front-end display of your site. This includes caching plugins. If the situation is improved, see the Check Plugins section of the 5 Step Solution<\/a> below for more detailed advice on choosing plugins.<\/p>\n 3. This may not be enough if your issue is related to script memory. If the problem persists, you will need to increase the PHP limit <\/strong>set in the php.ini<\/strong>. See your host documentation for how to do that. Below are links to documentation at popular webhosts:<\/p>\n Fatal errors are almost always due to a plugin conflict, the file is damaged, or the file is not compatible with a dependency. In most cases, the function will tell you exactly what the problem is, and in which file. You can interpret fatal errors pretty easily by breaking them down into four parts:<\/p>\n Some common fatal errors are:<\/p>\n This is caused by a plugin or theme using a function hook but the function not bein defined anywhere.<\/p>\n To solve it:<\/p>\n Similar to the above, except in this case the function is declared more than once instead of not at all. This happens if there are conflicting plugins activated, or if the theme or plugin author did not use a unique function name.<\/p>\n To solve it:<\/p>\n This message means there is a mistake in the code of your theme or plugins that needs to be corrected.<\/p>\n To solve it:<\/p>\n You can avoid this problem in the future by always testing custom code locally before applying it to a live site, or making a backup of the file you are editing first so it can be easily restored via FTP if something goes wrong. The Solid Code Theme Editor is helpful for showing syntax errors before you hit Save when editing via your WordPress admin.<\/p>\n This error is due to your PHP version being too low for your current WordPress version. Get in touch with your host and make sure your site meets WordPress minimum requirements.<\/p>\n Often times fatal errors that do not block access to your WordPress admin are just reporting a problem with the code in your theme or an active plugin, and are visible due to DEBUG mode being active on your site.<\/p>\n To solve it:<\/p>\n This one is almost always caused by the server configuration. Skip down to the 5 Step Solution<\/a> to troubleshoot.<\/p>\n Known affectionately as the “white screen of death”, blank browser pages where your website should be are the most frustrating thing to deal with, as they also block access to your admin panel.<\/p>\n The most common cause of this problem is a plugin conflict, either with another plugin, or with your active theme, or it may be hiding a fatal error you just can’t see.<\/p>\n To solve it:<\/p>\n If you right-click and view the source, you may be able to see this error, OR:<\/p>\n If any errors are available, this will allow you to see them. Don’t forget to set the value back to false once you solve your problem, or your visitors risk seeing all sorts of normal developer messages and errors, even on a working website!<\/p>\n If this does not help, you probably have a plugin conflict. Continue with the 5 Step Solution:<\/p>\n The following five steps solve just about any WordPress problem that is not caused by the server or bad code, or at the very least will help you determine what the problem is. Follow each step until your issue is solved or improved.<\/p>\n Having an out of date WordPress install or theme can cause a multitude of problems as files become unsynched or functions stop working because their dependencies have been removed or replaced.<\/p>\n Due to the open-source nature of WordPress, the code quality of plugins varies wildly. This leads to many common WordPress problems.<\/p>\n If this solved it, a plugin was probably the culprit. Rename the folder back to plugins<\/strong><\/em> and then visit the Plugins<\/strong> page in your WordPress admin. Reactivate your plugins one at a time, reloading your site in a new browser tab after each reactivation until it breaks (or hopefully doesn’t). This should help you narrow down which plugin triggers the problem. Simply repeat these steps again, then delete the offending plugin.<\/p>\n If your theme author has thoroughly tested your main theme, the problem is not likely inherent to the theme itself, but the theme may have become corrupted, become infected with malware or have a problem with your sever’s configuration that prevents your site from working. To ensure the theme files are sound, try reinstalling the theme and leave any customization or child themes out for now.<\/p>\n This file controls some aspects of security on your site, and how redirects work, including permalinks in WordPress. Some security plugins will modify this incorrectly or in too strict a manner which causes problems in WordPress. Your host may also enforce specific .htaccess rules that cause problems in WordPress.<\/p>\n For detailed .htaccess help, check out these .htaccess tips to speed up and secure WordPress<\/a>.<\/p>\n Sometimes the solution to a really tough issue in WordPress is to restore a recent backup, but that won’t help if you aren’t maintaining regular backups! In addition to backup options offered by your host, see this guide for keeping your Content Backed Up<\/a>.<\/p>\n One of the ways to streamline this process is to explore your managed WordPress hosting options<\/a>. If manage your site yourself, make sure you backup the entire site at least weekly and keep at least 3 previous backups. For sites that are updated often, make sure you backup the database daily and do periodic content exports as a fallback.<\/p>\n If all else fails, your problem may be with WordPress itself, or with the data in your database. Start by reinstalling WordPress, and if that fails, you may need to contact your host for further help.<\/p>\n WordPress is an amazingly stable platform thanks to the dedication and talent of the hundreds of professionals contributing to it, and the strict code standards they follow. Even so, the huge variety of themes, plugins and server environments out there make it difficult to guarantee nothing will ever go wrong.
