TinyMCE: Internal Server Error when uploading a new image Topic is solved

[WDJames]

Hi All,

We're having a weird one with TinyMCE. We are getting an Internal Server Error message when uploading an image via the Responsive File Manager on TinyMCE. The odd thing is that the image IS being uploaded to the correct folder but does not appear on the Responsive File Manager (the file is included on the files/folder count) on TinyMCE. I found out that it is not appearing because the file is not being copied into the "/tmp/thumbs/images" folder. The site is using the latest version of CMSMS (2.2.21) and TinyMCE (3.3.2) and is using php 7.4.

Anyone else having/had the same issue?

Thanks,

James

If you're using the sample htaccess file that ships with cmsms, there's a line you need to comment out/remove/edit as per the TinyMCE module help. If that's not it, check your php error logs to see what the actual error is.

I've tried that but the issue persists. Also, the error_log isn't being updated. For now, I'm manually copying the uploaded image to the "/tmp/thumbs/images" folder which sorts the issue but is rather annoying to have to do that. I've tested on other CMSMS installs on a separate server and can confirm that the issue is not present. Any ideas?

Without the error message it's hard to say, but it could be php memory, or a missing PHP module needed for creating the thumbnail. Check the admin log as well, and then compare the PHP plugins and settings to a site where it's working.

I've compared the php plugins and settings but found that there are more disabled php plugins on the site where its working. Also, the closest thing I have to an error message is (when I enable display_errors on the PHP INI settings):

SyntaxError: Unexpected token '<', "<br />
<b>
... is not valid JSON

The funny thing is that thumbnails are created when I use the default File Manager module. It looks like the error is more to do with the image not being copied to the "/tmp/thumb/images" folder on upload as I just copied an image to that directory (without the thumbnail file) and was able to see the image.

Found the error log:

I think that's the fileinfo (finfo) extension for PHP.

[WDJames]

Yup, I've installed it on the server which sorted the issue. Thanks for the help.
