J: 3.9.25
K2: 2.10.3

I have a user that got the error "call to a member function purgeprivate() on null" when attempting to login to the site and post an article.

The weird thing is they were able to login once and post. Days later when attempting to log back in they get the error. I've even gone as far as deleting their profile, creating a brand new profile then once created the same thing happened once again. This particular user has had a user profile to post for several years now and just recently in the last two or three weeks has this started. The other users have no issues with logging in and posting nor get this error.

There are no other errors but just a page with that error listed. This has happened in both Safari and Chrome.

Bumping this back up.

I got the same error recently. I think it was due to an incorrect login, but I'm a bit baffled too.

I'm using PHP7.3 are you?

I posted here: joomla.stackexchange.com/questions/28970/0-call-to-a-member-function-purgeprivate-on-null

No, I am running 7.4. However I test 7.3 at the recommendation of my web host with no change.

I have a feeling this may be a Joomla thing not a K2 thing as I'm not using K2

For me this is from Litespeed Cache.

I went into cPanel and I went to Terminal and I did a search by copying and pasting this (right click to paste)

grep -Ri purgeprivate public_html

It returns

$this->plugin->lscInstance->purgePrivate("com_virtuemart.cart");

    
If you are also using J2Store or Virtumart or another cart, it could be the same thing. 

I opened a GitHub issue here that you may wish to follow:

github.com/litespeedtech/lscache-joomla/issues/42

Because of PHP errors?

Aahhhh lost in textlation

I had litespeedcache installed but have since removed it and don't find any instance of purgeprivate running in the public_html directory.

Still waiting on confirmation from the user if the issue remains or not.

LS has been removed and the single user with the issue still reporting the error. I've had them try another browser, clear cache and even tried in private browsing.

I scanned the server files for anything related to LS and nothing returned back. Currently I'm running nginx web server.

None found. This is the return.

Again, this is not part of K2.
 

I did read the first line of the results. I'm reporting back that it did not find what you asked me to search. "[root@ssd public_html]# find . -iname "*.php" | xargs grep -i "purgeprivate(""

I got it, its not part of K2.
