Yesterday several users updated to Joomla 3.8 and immediately started having problems with some JReviews links not working correctly due to changes in the routing system even when used in Stable mode, which is the default, and meant no changes from Joomla 3.7.
I am attaching an updated JRevies SEF Plugin to fix this issue and also an error that appears when trying to edit modules in the administration. You can install it using the Joomla Extensions Manager. You should not enable the Experimental routing mode in the Joomla Articles / Options/ Integration tab because it will not work with the JReviews SEF Plugin.
Update Sep 28: If you use the Joomla language filter, then at this time the JReviews SEF Plugin will not work with Joomla 3.8 when the language filter plugin is also enabled.
Please report any additional issues you find below. If new issues don't come up, then we'll proceed to release an update that includes the updated plugin.
Update Oct 7: JReviews 188.8.131.52 was released and includes all the fixes from the attached plugins, plus a few more related to the Joomla language filter and the use of index.php in URLs. If you are using Joomla 3.8.x you are advised to upgrade to the latest version of JReviews and no longer install the plugins attached to this post.
