Media icons missing in editor after upgrade to v3.4.2. Have tried renaming plugins folder, problem persists with any theme and with plugins disabled. Do not know how to edit in SQL database but familiar with FTP. Website (www.robeya.com) is viewing fine but cannot edit anything - even text is 'blanked' out - have to highlight text in editor to see anything and then only shown in HTML. Appreciate any help. Tnx!
