Site is running EE 2.1.3 and I'm now getting WSoD on a few of my front-end pages (notably those with imgsizer plugin enabled, the other pages without images are working fine). I've read that it's a memory issue related to trying to generate a thumbnail with Image Sizer plugin (running 2.6.4) in this related thread but no solutions are offered. I tried upgrading to newer version that's been forked on GitHub but got the same problem. I've also changed the memory allocation to 512M and still no luck. Enabling debugging in index.php yields no PHP errors on the back-end and template files are parsing correctly.
This all started when I got an error message after a member couldn't upload a file (I'm assuming it was too large although I haven't heard back from them yet). The following error came from our server:
[19-Feb-2015 11:24:25 America/Denver] PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 17472 bytes) in /home/artdistr/public_html/system/expressionengine/third_party/imgsizer/pi.imgsizer.php on line 546
Now I'm getting a whole host of problems where paths aren't found (I'll only include one since there's a ton of them) from the server: Feb 26 12:24:22 2015] [error] [client 220.127.116.11] File does not exist: /home/artdistr/public_html/themes/template_variables, referer: http://www.artdistrictonsantafe.com/system/index.php?S=0&D=cp&C=addons_plugins
Thanks in advance, I'm totally stumped here.
