I'm using WordPress 3.5 on a multisite with the directorypress theme from Premiumpress.
My website randomly gives me a 500 internal error message. I did a lot of googling and in the end contacted my hosts.
They told me to check my error log. Well that was 132MB large and had the following message over and over:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/pdo.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20060613/pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0
They replied with the following message:
It seems you scripts were being killed by lfd for excessing usage of memory. Please find the logs:
Dec 28 12:28:18 panda lfd: *User Processing* PID:974195 Kill:1 User:ar01ickl VM:290(MB) EXE:/usr/bin/php CMD:/usr/bin/php /home/ar01ickl/public_html/wp-cron.php
I have exempted you from being killed as of now, which should fix the issue. However, we would strongly advice you to optimise your scripts from using too much of server memory, please seek assistance from web-developer/script vendor.
Now that may as well be written in Swahili as far as I'm concerned. Could you please help me as I can't get any further with them and am thinking I'll have to uninstall directorypress and that's the LAST thing I want to do because I love it so much!!!!!
I look forward to your reply. I do hope you've had a lovely Christmas. :-)
