You could be experiencing this after the cpanel upgrade and here’s how we got this addressed. This was throwing the crons out of gear as well. You need root access on SSH on the server.
[root@host]~ >> php blah.php PHP: Error parsing /usr/local/lib/php.ini on line 793
Open the file
Press ^_ and enter 793
Change the following line
url_rewriter.tags = a=href,area=href,frame=src,input=src,form=,fieldset=
to the one below or simply add the double-quotes
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="
It didn’t even require a restart.
