We are running zc 2.2.2 on php 8.2 and opc 2.6.2 now with some modsecurity rules disabled. most folks having no problem now, but we just had another that for some reason got a 500 server error during checkout. placed an order twice and still had the items in his cart. Is this possibly a common issue? Would it be resolved by upgrading to the 2.6.3 version. Also this is all with authorize aim.

If I'm to upgrade, should I just overwrite existing files, or is there db stuff as well? Should I use the plugin manager to uninstall and re-install?

Thank you,
John
