Any use? Read the whole thread, as there are other solutions posited. If that’s not useful, maybe try posting some more information. Joomla version and any modifications would be a start, along with any plugins.
The error information you posted tells you where to look. Unfortunately, that alone isn’t really enough. Unless someone’s encountered your error before (and, co-incidentally due to the same reason) you might need to put a little effort into describing your problem. Basically, errors tell you the what – you need to work out the why.
