I noticed since CMSMS 1.9.(?) TinyMCE shows absolute paths when inserting images. Having a long domain name and deep folder structure the name of the file gets cut off by the short address field
Is there a way to change that to relative paths (like it was in the past)?
I've encountered the same problem, and definitely miss being able to change that setting in the TinyMCE settings.
You 'can' still access the setting within phpMyAdmin.
Run a search in the 'cms_siteprefs' table on the 'sitepref_name' field, search for 'TinyMCE_mapi_pref_relativeurls' - set the corresponding 'sitepref_value' to 1 to turn on relative urls, and to 0 to turn them off.
NOTE: I found that the insert/edit image dialogue window would show the absolute path initially, and but once saved and re-opened it showed the relative url in instead.
It's frustrating and hopefully it is resolved on the next iteration of TinyMCE.
