Error message - The "" directory does not exist

[ethanlazarus]

I've just launched on our ubuntu 22 brand new server, but am getting a strange error message - very rarely, at random. Today I got it on logging out:

/var/www/cncchart.com/patient_chart/vendor/symfony/finder/Finder.php(649): The "" directory does not exist.

It is not occurring on the testing server running in Xampp...

I'm wondering if this is a permissions error? Any body know? Thanks.

Check your upload and log folder settings, make sure they are valid on your Linux server also.

Permission issue is likely, make sure the web server user has read/write permissions for the upload and log folders.
