Cache issue and fix for TypeError: Argument 2 passed to erLhcoreClassCacheStorage::store() must be of the type array, int given, called in /opt/livehelperchat/lhc_web/lib/core/lhtpl/tpl.php on line 547

Hi there, couldn't find an easy way to find out if someone has already reported this, but we came across an error that prevented LHC from serving any pages at all, including the login page.

We were able to solve it by modifying tpl.php in two places:

Line 202 becomes:

if ($this->cacheEnabled == true && isset($this->cacheTemplates) && is_array($this->cacheTemplates) && key_exists(md5($fileTemplate.$instance->WWWDirLang.$instance->Language.$port),$this->cacheTemplates))

and line 532 becomes:

if(isset($this->cacheTemplates) && is_array($this->cacheTemplates)) {
$this->cacheTemplates[md5($fileTemplate.$instance->WWWDirLang.$instance->Language.$port)] = $file;
$this->storeCache();
}

With these changes we were able to log in again.

Any idea what might have caused this? Anything else we need to do? I'm worried that there may be an underlying fault here.

Hope this helps someone!

...once we were able to log in again, we also had to go to Settings -> System -> Clean Cache in order to be able to see our chats.

I pushed theoretical fix. But in general it's even not possible to reproduce your issue.

Because this line always set's value as an array.

So something in general wen't wrong with your enviroment.
