Hey!

Today I installed K2. I have set up a category and wanted to add an articel. But I get always this error message:

Fatal error: Class ‘JSite’ not found in /var/www/virtual/mywebsite.de/htdocs/plugins/system/SEOSimple.php on line 153

It looks like K2 clashes with the Plugin SEO Simple (www.daobydesign.com/blog/seosimple-joomla-15-plugin/) which I am using already for some month now.

Has anybody an idea what went wrong?
Thx.
Dirk

Hi. Please make sure that you are using the latest version of K2. Similar issues have been posted in the past and have been fixed. So upgrading will probably resolve your problem.

I am using K2 2.0 release date August 6th. Is there a newer release available somewhere?

i have the same problem, the problem is in joomla CP

The Joomla Control Panel? Please explain.

I have the problem only in the backend. From the frontend I am able to submit new articles.

Hi. Similar issues have been posted and have been already solved. You can read more here. So please make sure you are using the latest version of K2. If you do then we have to do more research on this to find out what is causing this.

I have seen the thread but it is not solved. The solution was to uninstall seo simple. But I can't uninstall it. I just wanted to start with k2 but k2 is making the error and not seo simple.

Hi. Well it appears that is a SEO Simple bug. This is a system plugin but it triggers on the "onPrepareContent" event which normally is used by content plugins. To be more accurate K2 imports only the content plugins it needs ( SIG and AllVideos ) and then triggers the "onPrepareContent" event. The reason that SEO Simple is executed is because it is a system plugin ( always running ) and it uses a content event ("onPrepareContent" event should only be used by content plugins). The fix is quite easy and it can be done by adding a simple check in the plugin so it doesn't executed on admin sections. K2 cannot do nothing to avoid this. It is definitely a plugin issue.

Thank you very much for your help. I will contact the developer of SEO Simple again.

I was wondering if someone can share (or let me know the starting point that would let me figure out) how to:

'adding a simple check in the plugin so it doesn't executed on admin sections'.

Thanks

Thanks Mircea. I'm actually working with SEO generator, which I believe is having similar problem as SEO simple.

I tried adding your text, but did not work. There is currently, in the SEO Generator PHP file the following in the same place where you specified:

jimport('joomla.event.plugin');

I added your text, removed the above, tried with both jimport lines, and all combinations, but did not work. There is also the following in my PHP file:

// only mod site pages that are html docs (no admin, install, etc.)
if (!$mainframe->isSite()) return ;
if ($docType != 'html') return ;

I'm not sure if this is possibly the issue or related as well, but I'm getting the following error when I access K2 items in the administrator:

Fatal error: Class 'JSite' not found in /home/detroitr/public_html/organicproductmall/plugins/system/SEOGenerator.php on line 214

Thanks for your help--any other suggestions or thought? Jeff

This fixed the problem with SEOSimple.
Nope, sorry, no it didn't. I forgot what the problem was!! HA! Still cannot create new K2 items from the backend. When opening a new item, admin gets blank screen.

Didn't fix the problem for me, either.

Mircea, thank you! Your fix has now made SEO Generator work with K2! Awesome (not sure about SEO Simple-I don't use that). Jeff

Mircea said:sorry for late response;
You are right, for some reason it doesn't work for me anymore

Try this please:

after
function isFrontPage()
{

add

global $mainframe;
if (!$mainframe->isSite()) return;

Yep, this works for SEOSimple too. Thanks Mircea!!

Hi, I'm having the same problem between SEO Generator and K2.
I've added the two lines but now everything stopped working and finally had to disable SEO Generator.

In addition to the previous error displayed in the backend(sorry to not paste it here as it is toooo long), another 500 error displayed by sh404SEF shows on the front end:
SH404SEF : headers were already sent when I got control!
Killed at line 122 in sh404sef.inc.php: HEADERS ALREADY SENT (200)
URL=http://www.4xtechnicales.com/
OPTION=com_content
Don't know if this because of sh404SEF and SEOG or something else, but everything was working smoothly ill i added those 2 lines.

I'm using:
- Joomla 1.5.12
- K2 2.0 (dated 6 August)
- SEO Generator 2.1
- sh404SEF 1.5.2.254

Thank you

SEO Simple also doesn't seem to work with K2 on items that contain image galleries rendered through SIG. Instead of displaying the beginning of the item text as the meta description, it displays the item ID number as the meta description.

Hi,

Thanks for sharing

I can't believe it, but yes this works for SEOSimple! Thank you for sharing.
