I can not attach a file to a list or library. Moreover, it is impossible to attach only pictures, files with extensions jpg, PNG, BMP (any image files). when i trying attach files to a list item or library item and press the save button element, nothing happens, and the list item form does not close. after a long wait nothing happened If I try with other file extension, for example .docx,.xls,.wsp,csv,.pdf,.stp,.cs etc - these file are uploaded without problems. These extensions not in Blocked File Types. And these problem on all sites and all web applications on the server.
Also I have checked it on by creating a brand new team site but NO luck.
Any help will be appreciated.
