ERROR LOADING phpMyAdmin

Dear Sirs,   We downloaded WampServer onto our system on Tuesday this week but unfortunately, it has since seized to respond - later same day.  During attempts to load, it repeatedly presents this info: phpMyAdmin - Error; and on the next line: cannot load mysqli extension.  Please check your PHP configuration. - Documentation.  A follow-up to the link of ‘Documentation’ gives the following information:     1.20     I receive the error “cannot load MySQL extension, please check PHP Configuration”. To connect to a MySQL server, PHP needs a set of MySQL functions called “MySQL extension”.  This extension may be part of the PHP distribution (compiled-in), otherwise it needs to be loaded dynamically.  Its name is probably mysql.so or php_mysql.dll.  phpMyAdmin tried to load the extension but failed.   I have tried a number of efforts aimed at resolving the problem but to no avail.  Please help me with guidelines on how to nip this challenge to the bud.   Thanks for your assistance.   Regards,   Alexander Franklin.   NB:     It is practically difficult to reach the appropriate sections for attention.  Their email contact details are hard to find.  This is why I have decided to employ your medium.  Please help me forward this message to the quarters where attention would be forthcoming ASAP.   Thanks.
