My hosting provider upgraded its PHP version to 7.2 and they don't give any option to back to PHP 5.6.
After upgrading to PHP 7.2 I can't login to admin panel. Any suggestion?

What is the error message?
Did you or your hosting provider enable PHP extensions in PHP 7.2, similar to PHP 5.6, including mysqli support?
Suggest that you post the output from the Forum Post Assistant (FPA) by following the instructions from

Sorry, I did not realise that you are still using Joomla 2.5. It is not going to work with PHP 7.2. Your current third party extensions will not be compatible either.
You should start planning to upgrade the site to Joomla 3.x. The latest version is 3.9.3. There are upgrade guides in the forum 'Migrating and Upgrading to Joomla! 3.x' at

If you use Wamp on your PC it might be easier to migrate your site.

If I delete third party extensions can I login? Wamp looks complicated... Or is there any way to upgrade via FTP?

The authentication plugin needs to be enabled, otherwise you will not be able to login. However, if you try, you will see many notices, warnings and errors, but suppressing them is not going to make the site work any better.
Upgrading through FTP does not work.
The Wampserver bundle is well documented and the installation instructions can be found from the Wampserver forum at
http://forum.wampserver.com/read.php?2,138295. Wampserver allows you to set up a number of virtual hosts, install several versions of PHP and switch between them. Therefore it is ideal for testing templates and other extensions and running a local upgrade before updating the live site.
If Wampserver still looks complicated and you think you may need paid assistance from Joomla experts, post your requirements to the Professional Development Services forum at
viewforum.php?f=177.
