Some times we may get the following error in parallels plesk control panel:
ERROR: Allowed memory size of 16777216 bytes exhausted (tried to allocate 86 bytes)
This problem is due to insufficient memory for the plesk php. Some operation may require more memory for completing the task.
The resolution is to increase the memory limit
- Open the "/usr/local/psa/admin/conf/php.ini" file and increase the memory limit from there
- After changing the memory limit please restart the plesk panel
