I am hosting a website and both mysql server and web server running on the same Linux Suse box. The form submission is done through a php file on the server where users fill in the form on the browser and submit data to the website. My question is some users report that they get can not connect to my sql database error when trying to submit forms and I don't know what is the cause of this error because I can still get data from some other users. Please advise..
The php file uses username root and the appropriate password to connect to database inside. Hope that is what you asked.
I just realised innodb is not enabled on my.cnf file. Would it help if I enabled it ?

Go ask help on english forums thx http://forums.mysql.com/
