Speedtest shows I'm getting 12Mbps yet right now my blog dashboard is sticky, clicks taking an age to execute, various icons not showing (eg dashboard in widgets column), routine small picture uploads are landing in gallery but then cannot be inserted into page/post - only a white panel after clicking "insert". Repeatedly. This has happened before and I then have had to log out and return later in the day. I've restarted, disconnected, cleared the cache etc etc. Are there any quick fixes for this kind of stickiness?
The blog I need help with is shapersofthe80s.com.
