[FoxSecrets]

I got a lot of server errors and I'd like to understand and solve them.

Can someone help me how to debug this error?

Another question. What's the function of "forum/internal_data" folder?
There are several references to "internal_data/code_cache/templates/l1/s13/"
What does "L" and "S" mean? What happen if I delete all these contents?

Something in the xfrm_resource_list_macros template is trying to access a non-existent mgm_xfrmpp_conn property of an \XFRM\Entity\Category object, presumably stemming from a template modification.

What's the function of "forum/internal_data" folder?

The internal data folder is for storing (non-public) installation-specific data, including attachments, compiled templates, and sitemaps, among other things.

Language and style. If you delete them, pages which try to render those templates will not function as expected and you would need to rebuild the master data to regenerate them.
