Showing on the front end of an upgraded site with debug = true.Warning: preg_match(): Compilation failed: unrecognized character after (?< at offset 4 in /web1/user34855/website/lib/smarty/Smarty.class.php on line 1217
Fatal error: Uncaught --> Smarty: Unable to load template 'file:cmsms-error-console.tpl' <-- thrown in /web1/user34855/website/lib/smarty/sysplugins/smarty_internal_template.php on line 185
Background: This is a new client but an old site of theirs. Was running 1.9.2 with some errors, it was a mess. I copied over to my (good) hosting and upgraded successfully - it is working fine on my server at version 220.127.116.11.
Copying it back to their (not good) hosting, I get the above errors.
I have temporarily put phpinfo for their hosting here, they are running PHP 5.5.17:
What I have already tried:
Turned on debug.
Re-uploaded Smarty.class.php in case there was an FTP error on upload (no alternative to FTP on their hosting, sadly).
Cleared cache on CMSMS by deleting files in tmp.
Cleared browser cache.
