Then add the following lines: * ``` define('WP_MAX_MEMORY_LIMIT', '128M'); ini_set('memory_limit','128M'); ``` * Increase the memory limit to 128MB or more if necessary. * Thread Starter [great-taste](https://wordpress.org/support/users/great-taste/) * (@great-taste) * [10 years, 4 months ago](https://wordpress.org/support/topic/unserialize-error-2/#post-6739967) * Our hosting company, wpengine says we have it set to 512m. * I’m getting the Templates cache is not writable message on my settings page. Does it not need to be writable? I may be confused but my developer and i think/ thought that this may be why we’re getting memory errors. * I just added the ftp login in info to the wp-config file as I saw as a possible fix on another thread.

WPengine has the folders set to 775 and the files to 664. They refuse to allow 775 on files. * 2. When I try to switch months on the front end view I get the following error and this does coincide with the fatal error mentioned above. * Something went wrong while fetching events. The request status is: 500 The error thrown was: Internal Server Error * 3. Am i correct that if this is working properly when writing to cache old files would be overwritten but in this case where it’s not working properly new files are being created? * 4. What files can I delete and from where? * 5. Should this also fix the unserialize error above – sorry we got two subjects/ errors in this same thread. * Thank you, Teri * Thread Starter [great-taste](https://wordpress.org/support/users/great-taste/) * (@great-taste) * [10 years, 4 months ago](https://wordpress.org/support/topic/unserialize-error-2/#post-6740104) * It’s my busiest calendar season of the year and it’s not working. PLEASE RESPOND and help me figure this out. * Thread Starter [great-taste](https://wordpress.org/support/users/great-taste/) * (@great-taste) * [10 years, 4 months ago](https://wordpress.org/support/topic/unserialize-error-2/#post-6740122) * [@benjamin](https://wordpress.org/support/users/benjamin/). I really hate to have to do it but it looks like I’ll need to try another plugin instead of the all in one event calendar. I’ve been with you for years and for the most part have had my developer fix most of the bugs we’ve found since tech support is so lackluster. I’ve tried un-installing and re-installing but just spend hours trying to fix it with no positive results. Why do you refuse to help me? Not once, with all the errors above have you asked for my login creds so you could have a look and perhaps fix this. You used to be more of a help and I see that you do this for others. Please don’t force me to move on. HELP ME, I have thousands of events and site visitors and will only leave if you force me to. Please respond immediately. This has been going on for weeks.
