RSJoomla! Blog - tutorials, tips & updates about bug

After updating to Joomla! 3.4.0, you may have encountered some extensions that did install in previous Joomla! versions are now throwing the message:

What is causing the error

Joomla! 3.4.0 introduced a new security feature, scanning uploaded files for potential dangerous code. For example, it scans uploaded archives for PHP code - something that should not be done in the Extensions Installer (com_installer). Fortunately, Joomla! contributors already debugged and fixed this (pull request here) so if you don't want to wait until 3.4.1 is released, read this blog post.

An issue recently introduced in Joomla! 3.3.4 (pull request here) makes navigating back to the first page impossible when using SEF. When you click to go to the second page and then attempt to go back to the first page, you'll actually stay on the same page. This is because the "limitstart" parameter is missing from the URL due to this cosmetic change (which attempts to avoid duplicate URLs). They're fixing it in the upcoming 3.3.7 release (pull request here).

Read on for instructions on how to fix this.
