Offending extension using its own jQuery library detected (see manual, section "Limitations").
It is referenced here: http://www.cmsimpleforum.com/viewtopic.php?f=7&t=6351
but no fix is explained for us laymen.
The site I have it on is: http://www.memorablemomentshire.com
Edit: Solution found.
I have added a <script> tag in my <head> area for loading a Google Maps element:
Code: Select all
<!-- 20150107 jQuery library (served from Google) -->
If I comment this out of the template the PageManager loads fine.
Seems like I don't even need those <script> lines for my google maps to work.
