The same problem, the same error with K2 2.6.9 and Joomla 3.4.1 (fresh install, no third-party extensions).

Set error reporting to "Development" in Joomla's Global Configuration, go to site.com/administrator/index.php?option=com_k2, we get

Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in administrator/components/com_k2/k2.php on line 20

The same problem happens with K2 2.6.6, 2.6.7, 2.6.8.

However, if you use an older version of Joomla, everything is good.

To work around, I installed Joomla 3.2, installed K2 2.6.9, everything was successful, then update to Joomla 3.4.1. Now K2 works.

P/S: I just submit and hope the submitted info is helpful, I don't need help.

The error log indicates that the K2 system plugin is not enabled. Enable the system plugin and everything will work fine.

web-seo commented 9 years ago

Kavadas, is not due on system plugin. The same error also on one of our clients sites with latest K2 and latest Joomla 3.4.4 - error was present immediately after install. Solution: open plugins page, search for k2 - find k2 search plugin and K2 smart search plugin and disable both plugins. After this K2 will work.

JoomlaWorks team must think about this issue in next K2 version. This happened only on servers with activated FastCGI.

Cheers from Bulgaria.

@web-seo

Can you provide more details on this? Just tested under Joomla! 3.4.4 with both Finder and Search plugins enabled and i see no issues.

web-seo commented 8 years ago

I can't reproduce it, we use K2 only for testing purposes - to test compatibility with our Joomla extensions. I read in some russian webmaster forum that this happened only on servers with activated FastCGI. Is true - on server where we test ( http://androidappsdeveloper.net/ ) FastCGI is active.

Considered fixed with this https://github.com/joomlaworks/k2/commit/fd0464865deb2bb572a56192577876a01265e651 .

@kavadas, thanks, will try it.

If you disable Cache Settings in (Global Configuration - System), then reinstall K2. Open anything in K2.. Then go back and Enable (Cache-Progressive) and set the Time to 60.. It should work..

web-seo commented 8 years ago

@orangeNapples, Progressive cache in Joomla is for users only and give poor results with site speed performance, conservative cache is the right setting
