Hi borimrr,
Just wondering did you manage to get a short code working for Smooth Slider? Could you let me know what it is?
Cheers
I had a similar problem with slow performance on new or editing post / pages and I tracked the problem back to a plug in called Keyword-Statistics. It’s an auto generator of keywords etc from your post and a lot of my posts had a lot of information in them so Keyword-Statistics was working overtime with the database and generally being a pain in the arse.
Once it was uninstalled , hey presto everything was back to normal.
Other than that can’t help if the problem is else where
It’s ok , I uploaded 2 files, plugin-editor.php and theme-editor.php from WordPress Trac and all is well.
