A client recently contacted me to say they got a 500 error when trying to access their Magento 1.9 admin.
My first idea was to refresh the cache manually. This worked.
It sounds like they might not have logged in in a while, but why should not logging in or not clearing the cache make the admin inaccessible.
The associated error message was:
PHP Fatal error: Maximum execution time of 30 seconds exceeded in /lib/Zend/Cache/Backend/File.php on line 679
Here's a link to the file producing the error: https://github.com/OpenMage/magento-mirror/blob/magento-1.9/lib/Zend/Cache/Backend/File.php
I understand that the max_execution_time has exceeded and that increasing this time might help, but I want to understand why it exceeded in the first place. It should not need 30s+ to access Magneto admin so there is obviously an issue causing the timeout.
Any ideas would be helpful.
Thanks in advance :)
