I have several wordpress sites installed with separate databases located on an intranet. They all have the version 3.8.1. All web sites worked for a couple weeks. Last week I looked at one and it had the above mentioned error; then I looked at all of them and same thing. I have gone through everything I can find on the web and your forum and nothing is working to fix this problem. I am the only one who has access to this server so there is no chance of passwords being changed etc. I have a separate, much older site with version 3.0.1 which is perfectly fine. Any help would be greatly appreciated. Thank you.
