No such file or directory in file w3-total-cache/Cache_File_Generic.php

Hi,

I’m hoping I can just get a second pare of eyes on thisproblem I’ve been struggling over the weekend. Basically I’ve been palgued with checkout errors on my ecommerce website. Customers will just get a generic “Internal Server Error” when entering their credit card details.

I enabled error logs over the weekend and was able to reproduce the error. It seems like there is a conflict of sorts between W3 Cache and WP Product Feed Manager plugins.

Here is the error log:

[17-Sep-2018 09:48:17 UTC] PHP Fatal error:  Allowed memory size of 94371840 bytes exhausted (tried to allocate 20480 bytes) in /home/dynam825_cumbriawhiskey/houseofmalt.co.uk/wp-includes/meta.php on line 846
[17-Sep-2018 09:48:17 UTC] PHP Fatal error:  Uncaught Error: Class 'WPPFM_Feed_Controller_Class' not found in /home/dynam825_cumbriawhiskey/houseofmalt.co.uk/wp-content/plugins/wp-product-feed-manager/wp-product-feed-manager.php:323

So I went to the wp-product-feed-manager and looked at the error log there:

I am afraid I am not sure what to do next, other than disable the W3 Cache plugin. I don’t know where the fault lies either, or if I have configured the plugin incorrectly. If anyone can shed some light on the matter, I would be most grateful!

All the best,

Jethro
