A few more details.... I'm able to write to the DB with some pages, but not with others. I updated the security assist page settings, as I found it was improperly coded, but that appears consistent on both pages.
When I attempt to update the record, the page freezes for a long period and then shows the 500 error. When this happens, it appears to crash the entire site as I can't even access the home page or I get the same error.
I've reached out to the host but base level support is scratching their head and has escalated it up the chain. Just wondering if you have any thoughts from your end.
