While using Joomla 3 for creating some articles I was getting Lock Table error in SQL and the articles were not getting posted on server. There was no error on localhost though. This error was not a joomla template specific I guess. It was occurring for other templates as well. But I found solution to this error as follows:
Access the template folder of that particular website through FTP. Right click on the folder and make the numeric value for file permissions as 777 and apply to all files, directories and folders. This solved the above error and the articles were published successfully.
