Joomla管理员无法打开：“无法加载动态库...”

Question

I have uploaded my Joomla site in live server. When I open its backend, it asks for a username and password.

After login, it opens a blank white page but the front site is working fine. It also works in my local server.

When I see the error log in the SITE_ROOT/administrator/error_log file, it displays these errors:

[04-Jun-2015 11:59:14 America/New_York] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/soap.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/soap.so: cannot open shared object file: No such file or directory in Unknown on line 0.

Answer 1

Try to enable this extensions in php.ini if that possibility exists. Or if you have ssh access - log in via terminal and install this extensions (yum install php-soap). If your server doesn't support this - maybe you should change hosting provider.

Answer 2

This is a common error when you have old code running on a newer version of PHP. If you are on the current version of Joomla (really anything recent) it is not coming from the core, it is coming from an extension, probably a plugin. Yes, look at error reporting but also you can disable plugins you have added one at a time until your find the one causing the problem.
