I recently updated my wordpress for no other reason than I was prompted by wordpress to do so .. big mistake. The upload seemed to crash and I couldnt log back into my dashboard .. my site was still up but it was slow and gave the appearance that I was still logged into admin. I checked the forums and it appears that this is a common problem the general advise seemed to be deactivating plugins, reloading wp-admin and wp-includes.
Did all this and nothing worked just got a different set of errors and lost my site entirely.
By the way my site is hosting on godaddy for my sins and their advise was to reload wordpress and start again ... which i did (saved wp-contents first). This hasnt worked either. Its now a great big Cluster F**K. My Macs about to go off the balcony. Can anyone help make sense of this for me.
