I’ve noticed that we are running v2.0.14 of SMF here. This version is about 6 years old now, which in computer software time is quite ancient. I also don’t know if any patches or mods have been installed since 2.0.14 was implemented.
Though I’ve not been able to find any definitive documentation that would support it, maybe upgrading the forum to a recent version would help with this issue? We may not need to go right to v2.1.4 (the latest) but I think moving, even if gradually, towards it might be a good idea.
Just one IT professional’s opinion.
