phpMyAdmin message

[ROUBOS]

Hi, getting the following message on phpMyAdmin on a newly created database:
"Your PHP MySQL library version 5.0.90 differs from your MySQL server version 5.2.4. This may cause unpredictable behavior."

How much of a problem can this be? Should I mention it to the hosting providers?

Also cannot connect when testing the FTP during Elxis install. Even though the /var/www/vhosts/kalymnos-news.gr/httpdocs/installation/tmpconfig.php is writable. The FTP works fine with FileZilla.

any thoughts?
thanks

Yes you must mention that.
