Hi Damon,
I'm seeing this issue when the error logs get big - not sure what the threshold is. Last time I experienced it (a few minutes ago) the error log listed (86) records. Even after clearing out the error logs on the server within the root directory as well as the CMS directory I haven't been able to get the front end of the CMS to recognize the cleared error log.
In fact, attempting to load the error log from the CMS and getting the blank page creates this error in the log:
[04-Dec-2015 08:37:26] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 3660650 bytes) in /***/***/***/***/cmsb/lib/viewer_functions.php on line 433
This CMS was just upgraded to 2.65 yesterday after a full backup. Error logs were working fine with low error numbers. My high errors were caused by the "Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/'" which I've since remedied.
____________
Update - I've reinstalled 2.65 and I still cannot access the error log page. It's just a blank white screen.
