Update / upgrade site's scripts to work in PHP 5.4

Project: Update/upgrade site's scripts to work following server moving from PHP 5.3 to PHP 5.4. Two identical sites. Also update the phpadmin version from 4.0.10.7 to 4.5.3.1 Details: I have an issue with my 2 (identical) websites. After my hosting company upgraded PHP version on the server from 5.3 to 5.4 I can still access my 1st page of the website, but then there are some issues with the scripts and cannot get further. Cannot select a province and language to show the products for that province. I would need someone to look at this and update/upgrade the site's scripts. Also to update the phpadmin version. Websites: [login to view URL] and [login to view URL] I asked around and these may be the issue (other opinions): 1. Actually the problem is with your [login to view URL] file which is supposed to fetch data from mysql and pass it to [login to view URL] file, but it is not fetching data regarding localization. Actually on [login to view URL] it sets the localization and redirect the users to [login to view URL] file, [login to view URL] file is included in [login to view URL] file, [login to view URL] expects results from mysql database but its not getting so keeps user redirect back to select.php. Hope it makes sense. It can be the problem of PHP or MySQL version or a code issue, it has nothing to do with PHPMyAdmin 2. Seems that php extensions got uninstalled on your server or some misconfiguration was made, I can see an error on the [login to view URL] file, and in the logs, the mysqli extension is not loaded, can you create a php file containing the following: <?php echo phpinfo(); ?> with that we can now exactly if there are some missing extensions(modules) in php 3. I think, your Error is in [login to view URL] line 79 4. It seems like your array hold no data 5. Looks like a "proper" mis-configuration of php and some files being deleted on top of that Can you please let me know how much it will cost to have this fixed as well as upgrading the phpadmin to the latest versions. How long it will take? See the error log msg in the attached file Thank you!
