Firstly provide a bit more details: what version are you using: SMF version, Tinyportal version, PHP version?
Software Version: SMF 1.1.21
$forum_version = 'SMF 1.1.21'
(from the index.php can't find the TP version)
PHP is up to date, but the host tried loading an older version, and that didn't work either
What other mods are you using?
None that I can remember
The error is not pointing to TinyPortal...
I had some problems with trying to update the SMF, with errors showing on multiple lines, so it was inadvisable to go ahead. I made the mistake of not taking it further because it was working OK without the update.
What led to the errors?
I didn't do anything to bring it on. I'm guessing the hosts just updated PHP
I assume you moved to a higher PHP version? What version was working last?
I've no idea -- I leave that to the hosts. I can find out if you need to know.
Easiest approach would be to downgrade to the php version that was working and when the forum comes back take it from there...
Yes, tried that. I was hoping I can somehow find a way to upgrade SMF or TP without having to use SMF package manager, as I don't currently have access to it due to the fault.
Many thanks for the reply, @rjen
