#2786 – jos-Error: Sorry, but this page isn't available.

Hi

1 - What's the history of the site? jos-error is something that does not exist in Joomla 3 anymore, it's been removed long time ago
2 - At some point there was some problem in an sh404SEF update: you still have the sh404SEF custom content category, and the __404__ article.
[xxxx]

These 2 also were removed a long time ago, and we do not use at all that mechanism for displaying error pages. This changed like 2 years ago I think.

Ahh, ok. May have found something:
[xxxx]

Please update your site to the current Joomla database. You are running your Joomla with a database schema from Joomla 3.4!

Cant' say that's the problem, but it sure is one big problem to solve first.

Hi

So we are back to the first questions:

1 - What's the history of the site? jos-error is something that does not exist in Joomla 3 anymore, it's been removed long time ago

2 - At some point there was some problem in an sh404SEF update: you still have the sh404SEF custom content category, and the __404__ article.

The article and category should be deleted, but they should not cause any issue either.

I don't know what to say: I do remember this happening, a long time ago, and we found workaround for it. I don't know why your site is doing this.

What we could do is as follow:

- take an akeeba backup of the site (exclude some directories if the backup is too big, it should not be bigger than 2 or 300 MB, otherwise it's hard to download and manipulate reliably).
- we'll download that, and install on a local machine, where we can step through the PHP when the error happens

This will allow understanding the problem and find what's causing it. I don't think it's within sh404SEF, as we have had this feature for many years, but you have many plugins and a custom template, so there's room for some interferences here

Hi

So this is caused by Easyblog: the Easyblog router has a problem: it fires a 404 when it cannot parse a URL, and this is a big issue. It bypasses entirely the Joomla API, and it should not.

The problem is at line 868 of the file /components/com_easyblog/router.php. To fix it change:

	if (! $vars) {
		// someting is not right here.
		return JError::raiseError(404, JText::_('COM_EASYBLOG_PAGE_IS_NOT_AVAILABLE'));
	}

into:

	if (! $vars) {
		// someting is not right here.
		// return JError::raiseError(404, JText::_('COM_EASYBLOG_PAGE_IS_NOT_AVAILABLE'));
	}

(ie comment out the faulty line).
