local 2.0 prevents access to remote PhpMyAdmin? Help!

Bonjour a tous le monde; my french is not that good, so would you pardon me for using English..

Can anyone please help with this problem?

Here's the data:

- Local machine, Win XP.
- Remote hosted Php/MySQL web site, Php site on server A, MySQL on server B; both servers A and B provided by same Hosting company.
- Php site accessing MySQL via Php code just as usual, no problem at all, site perfectly working.
- Direct access to remote MySQL database from local machine via a remote interface provided by Hosting company: PhpMyAdmin 2.9.1.1. No problem until this problem showed up.

- The problem: I log in to the remote PhpMyAdmin, no bad login messages, and instead of accessing the remote database I land on this error message:
----------
Welcome to phpMyAdmin 2.9.1.1
The reason for this is that you probably did not create any configuration file. You may want to use setup script to create one.
Error
Messaggio from MySQL:
#1045 - Access denied for user 'apache'@'localhost' (using password: NO)
----------

More data:
- this problem affects ONLY THIS local machine: I can access the remote MySQL via the remote PhpMyAdmin above without any problem.
- I previously had EasyPhp 1.7 installed on THIS local machine, and everything went always good: never had any such problem. I replaced EasyPhp 1.7 with EasyPhp 2.0 and this problem showed up. I uninstalled EasyPhp 2.0 and reinstalled EasyPhp 1.7 and the problem is still here unchanged.

I do not know whether:
1) EasyPhp 2.0 may create any kind of interference with accessing any remote MySQL, and
2) Whether EasyPhp 2.0 leaves some undeleted traces somewhere in the system when uninstalled that may perpetuate the problem.

Does anyone has any idea about how to solve this problem.
Please help!

Thanks a lot in advance!

Dear All, it's still me just to better specify something above:

under "More data" above, I did not specify that while the problem affects only this local machine, this means that any other local machine does NOT have any problem at all in logging in and accessing the remote MySQL database.
