In WordPress if the error “Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate xxxxx bytes) in /wp-admin/…….” occurs it is a memory error relating to PHP. What has happened is that the allocated memory has been used up.
Most hosting providers set this to a low level and when WordPress/ WordPress plugin or custom script requires more memory to action a PHP request it results in a fatal error.
To fix
– log into your hosting provider via FTP or cPanel
– go to the webroot directory such as /public_html or /htdocs
– create a new file and name it php.ini
– add this line of text and save
memory_limit = 256M ;
Now the error should be gone!
If the error still persists you need to request your hosting provider to increase the memory limit for you – if they won’t maybe time to look at alternative providers.
