The following error comes up when I use phpGrid. I've seen this error on the Internet several times but no one seems to have a decent solution to it. Any ideas?

Warning: mysqli_real_connect(): (28000/1045): Access denied for user 'root'@'localhost' (using password: NO) in /var/www/html/phpGrid_Enterprise/server/adodb5/drivers/adodb-mysqli.inc.php on line 113
Error: Could not connect to the database

Oh come now! I just did a search for "'Access denied for user 'root'@'localhost'" and got 417,000 results... pick one!

Answer: Configure it to use the mysql 'root' user's password.
(or any valid mysql user/pass combination with access permission to your database).

On the off-chance that you do not yet have a user configured in mysql, read on...

If you are not familiar with mysql and have not set up a mysql user, search for "mysql grant syntax". But to make it very, very easy for you it will be something like this...

...then in your application configuration file use these same parameters to connect with mysqli_real_connect().

And welcome to LQ!

When I dropped the phpGrid folder into the Linux box, I had a new name for it other than phpGrid, that being phpGrid_Enterprise, because I didn't want to overwite the previous folder. Once I corrected that little issue in several PHP programs, things worked perfectly. I had alrady set up the MySQL database, and rights, etc. I appreciate your response, because what you wrote are things that I may sometimes forget in a rush to get something done. Thank you, AstroHGeek for your response.
