We are running a WP 3.9.1 multisite network with about 50 sites on it. Advanced Access Manager is activated individually on all sites and configured individually.
Recently purchased all the extensions and upon activating the Media Manger extension two other plugins displayed symptoms of being broken. Deactivating the Media Manager eliminates the issue with both other plugins.
When Media Manager extension is activated, then the thumbnail sizing no longer works on plugin Special Recent Posts Pro. Regardless of the dimension settings in thumbnail options the images in Special Recent Posts Pro display at full size.
And when Media Manager extension is activated the thumbnails on WordPress Popular Posts will not display; only a broken image placeholder displays.
The issues with these plugins only occurs when Advanced Access Manager is activated with the paid extension Media Manager also activated.
It may be a configuration setting that I have not yet discovered, etc.
I have reported this to all three plugin authors in hopes of a resolution.
Any assistance will be greatly appreciated.
