update of wordpress came with error and i cant log into y site

Try switching to the Twenty Eleven theme and see if that works.

Thanks Bostonwordpress, the problem is that i cant log into my dashboard, every time i try i get that same error message.
Any idea how to get around it?

Then try disabling all plugins by renaming your plugin folder and see what happens

Sorry, im not as computer savvy. How do i get to that stage? see anything i click to get into the dashboard or even my account i get that same above message, its blocking every access i try.
will you be able to walk me through a solution?

Here are the instructions:

thanks, i was able to get to my FTP file manager (which until now i had no idea what is it and where would that be :)) and fix it all from there.
thanks again Boston WordPress!!!
