Okay, we are still having issues (after 7.0.4 udate). Unfortunately the issues have not be completely resolved. We have issues with all jReviews URLs containing a number, e.g.:
www.opgroeigids.nl/kidsgids/basisscholen...-voor-basisonderwijs
ONLY when we enable the OpenGraph plugins for Content and jReviews. See attached.
This is what I got from Alejandro at jReviews:
"The issue is caused by the JFBC Open Graph JReviews and Content plugins for URLs that begin with numbers so if you disable those the page will load. It started happening only with Joomla 3.6.2 which made some changes to the way Joomla routing works and something in the JFBC code no longer works as before. We faced a similar issue with our JReviews SEF plugin. They are already aware of this issue because we wrote to them and I believe they are working on a solution. We've spent a good amount of time troubleshooting this problem and unfortunately there is nothing that we can change in our code to get around this problem."
I have it currently disabled on our site as we can not afford further 404 issues...
Really hope that we can get this resolved as soon as possible.
