SoftException UID is smaller than min_uid

Im getting errors in my log file.

Stunningly descriptive post! 
You have the wrong ownership of some file(s) - it'll tell you which ones in the log.

lmao.  I wondered.   A zebra never changes its stripes, especially yours.

Just for you I will include the error message.

SoftException UID is smaller than min_uid

I googled that and already learned about your solution before you posted.

Using fix permissions did not change anything.  So, either fix permission script is bad or it is something else above my paygrade.

Draws blood from a stone..
Which log? What is the message just prior to that?
You have an application (PHP, HTML, script) that is running at too high a privilege (possibly root).

My car has broken down - could be any number of reasons. 

Its the error.log.  It hasnt happened since oct 3 so maybe its no longer a problem.  I may have over reactivated. 

@Namaste, the error means your files owner root (I guess you have uploaded them under root user). You must use the chown command for the files.
Fix permissions feature will fix the permissions and not owners.
