Uploading images no longer works

    I have been using Solid Security Basic or iTheme Security for several years on dozens of installations and in the most recent installation the plugin blocks the upload of image files larger than a few KB. I get the error message:

    “Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page.”

    Unfortunately, uninstalling the plugin doesn’t help and deactivating the individual setting didn’t help either. Only a complete reinstallation of WordPress without Solid Security was able to solve the problem.

    • Everything is up to date
    • I’ve tested deactivating other plugins and themes
    • debugging doesn’t throw up any errors
    • testing by the host didn’t reveal anything either
    • Permissions on the server are correct
    • PHP memory is sufficient for frontend and backend (v 8.2)
    • There is enough space on the server and there are not too many files

    Unfortunately, I couldn’t find a suitable thread for this and I’m grateful for every idea.

    The problem was probably only temporary, today it works again with the standard settings. I mark the post as solved. If anything changes here, I’ll let you know.

    Hey @creation498!

    My second favorite type of issues are ones that resolve themselves. (my first favorite are bugs that we catch in Quality Assurance before we even send them out in public)

    Glad to hear this is resolved. If you need anything else at all, we’re happy to help.

    For reference, the error message you supplied in that first message is one that comes from “above” (or “below” depending how you visualize the server stack) PHP or WordPress, likely from the NGINX level (according to my brief web search for the error). So it’s not an error message that Solid Security itself is generating. I do find it curious that it was resolved by reinstalling WP without Solid Security, but I am working under the assumption that that was a cooincidence.

    Generally speaking, the next time you’re troubleshooting an issue that you have a suspicion is caused by Solid Security, adding this line to wp-config.php will completely disable anything that Solid Security is doing (whether it’s active or not):

    define('ITSEC_DISABLE_MODULES', true);
