My website installation is quite old, more than 2 and a half years and I have been updating the WP with every respective update.
However off late I find my website is running very slow and many times I get code warrnings (on admin panel) along with various other problem also.
I wish to clean up my code (plug in / theme and any other manual mods done by me).
I wish to keep my post data and just couple of essential plug in and its database foot prints and delete / clean everything else.
(the URLs / WP super chache plugin)
Can anyone suggest the process about it ?
