    Hello,

    After migrating a website using UM from an NGINX server to one running LiteSpeed photos can’t be uploaded by users. In Chrome I just get “ERROR” and one of the users gets this (not sure which browser he’s using though):

    ERROR: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

    I’ve tried disabling other plugins that might be conflicting, like Ivory Search and Ninja Forms, but no dice…and everything worked on the development server (same versions of WP and plugins).

    Hi @orabidoo

    Have you tried using a default WP theme and see if this is a conflict issue with your theme?

    Yes, switched to the latest standard theme and got the same error.

    It appears to be mod_security running on the new server. The administrator turned that off and now photos can be uploaded.

    So is this error with Ultimate Member or is it a settings issue?

    Hi @orabidoo

    It’s a compatibility issue with your server configuration. Thanks for letting us know how you resolve the issue.
