This has been going on for a while no matter what update I install. Am at current update. I have removed all template-c files except index as someone previously suggested and regenerated the template files. I have updated all modules including system. I have un-installed and re-installed offending modules only. I've been afraid to turn off modules that are frequently used for fear they also will not show up. I can still administer the offending modules by clicking on their installation icons, so they are still able to be used but that is a pain in the butt. Any suggestions? The modules that won't mount are : anything new that I try to install now as well as Liaise, extcalendar, contact us, forum, so far. Would like to install protector and paypal donations but have hesitated.
