Hi guys. My website is not working anymore and keeps coming up with the following message:

WARNING: An Error occurred, please refresh the page and try again.

I have researched and have found that looking at the error logs will determine what the cause of the problem is but I am finding it to hard to interpret exactly what the problem is and I am a little confused on what steps to take as I do not want to make anything worse. If anyone could help me on this on how best to fix the problem I would greatly appreciate it.

Thanks
