We have a custom module that a developer created for us that has some issues that need to be corrected.
#1. When trying to checkout for certain products an error: "Fatal error: Uncaught Error: Class 'modulename\Vendors\Model\XMLWriter' " -- note that XMLWriter is installed and enabled. Code may need to be modified.
#2. Same module does not have a magento cron job to run on a schedule. Magento cron is installed and running. There are feeds that need to be run on a schedule and are not running.
Categories load time is over 10 seconds - using profiler we can see where the bottleneck is, however even after disabling the offending modules the performance was still slow and broke some site elements so it was renabled. We need to get this issue fixed.
