The following are the actions taken that were not sucessful:
1.Deactivate all plugins
2.Deletion of all files after backing them up, and uploading it back to server again.
3.Changing of current themes used (Suffusion) to Twenty Eleven theme and reverting it back again.
4.Clear cache of all browsers
5.After searching for the posssible solutions, changing set mysql.trace_mode = Off in php ini might be possible. however, it was already set in default in txt. file and we don't think the file is related to the problem of our wordpress.
We have tried all prossible solutions after searching/reading forums but to no avail.
Can any kind soul please give us some suggestions?
