Compiling user report causes fatal error:

If the site is near it’s assigned memory limits, the cache rebuild or refresh can throw it over the edge. The only way around that problem is either increase the memory or reduce the requirements. There are various places where memory limits can be imposed, best to check them all. If you go to the plugins settings > General > About, then you’ll see info on your system. Lok at the limits AND the php version being used.
eg:
Php version: 7.4.6
Wordpress Memory limit: 256M
Wordpress Max Memory limit: 256M
Php Memory Limit: 256M

To reduce usage, you can do things like:

• check in your hosting control panel whether you can upgrade your php version,
• disable inactive or unnecessary plugins

There are a variety of other suggestions when you google https://www.google.com.au/search?q=Allowed+memory+size+of+268435456+bytes. Here are some:

Also under plugins settings > general, you could see whether the other “How to fetch data?” option makes a difference, although I think it won’t make that much difference.
Longer term I am working on a real time query version which will use less memory (but maybe at the expense of speed – sigh)
