Big thanks to those that helped and especially the module developer. My customer is happy now

Thank you for your response and help. It seems that there is a failure/compatibility issue in the payment module. I am having the same issues as the data center engineers. I'll quote back their response. I can see that same message now by following your guide. I have tested to changing the permissions to "a+wr" and checked the orders but still the same error. Sessions are being created even with the proper permission we set. Based on the error showing, "An exception has been thrown during the rendering of a template ("Unable to load template 'file:helpers/list/list_header.tpl'")." It seems that the system is unable to load the file list_header.tpl. Could you please verify that on your end?

Thank you for responding. This provided access to the backend but I can't keep it on a server that is shared because of security reasons. Has resolved some of the errors but the backend has errors popping up in customers, orders, and possibly others. I'm still looking for other options to resolve all of the errors. I don't find the modules that were installed in the list in the backend so now that I can get in, I may re-install both to see if that helps. as a last resort I may see if I can use the auto update within the backend as 8.2 is available and this install was 8.1.7. This might introduce more issues but at present a full remove and reinstall is the only option and since my customer has made changes to their store, has 500 items, 8 years of transactional data, and close to 1000 customers in their database I really don't want to set them back to "start". Thank you for your help. It has allowed me back in to. Screenshot of non-expanded list of errors in the orders section.

Can I re-install without overwriting the database content?

All went well. New install. Added 2 modules and still all well. Started running test sales and bam. No more back end.
