Hi, 

Access to WHMCS is unstable (http://visageweb.com.br/financeiro/admin/). Sometimes it accesses normally and seconds later it shows the error below:

=================================================================================================================

Oops!

Something went wrong and we couldn't process your request.

Please go back to the previous page and try again.

Whoops\Exception\ErrorException: Module 'pdo_mysql' already loaded in Unknown:0
Stack trace:
#0 /home/visag391/public_html/financeiro/vendor/whmcs/whmcs-foundation/lib/Utility/Error/Run.php(0): WHMCS\Utility\Error\Run->handleError(32, 'Module 'pdo_mys...', 'Unknown', 0)
#1 [internal function]: WHMCS\Utility\Error\Run->handleShutdown()

 

=================================================================================================================

 

I do not believe to have relation with the module since it has moments that the access is carried out correctly.

SOLVED.

 

Upon my review I found that WHMCS was loading PHP extensions from an old legacy PHP 5.6 installation at '/opt/php56', in both '/home/visag391/public_html/php.ini' and directives added to the .htaccess file at /home/visag391/public_html/.htaccess. I also noticed that the PHP extension tidy was being loaded on the cPanel EA4 Installation of PHP 7.0, although the extension was missing. I've since reinstalled the extension and as a result I was to load http://visageweb.com.br/financeiro/admin/ without error. The steps performed are detailed in the following. 

root@server01.visageweb.com.br [admin]# mv -iv /home/visag391/public_html/php.ini{,-$(date +%s)}'
`/home/visag391/public_html/php.ini' -> `/home/visag391/public_html/php.ini-1526518480

root@server01.visageweb.com.br [admin]# grep 'opt/php' /home/visag391/public_html/.htaccess
php_value include_path "".:/opt/php56/lib/php";"

root@server01.visageweb.com.br [admin]# sed -i-$(date +%s)} '24,92 s/^/#/' /home/visag391/public_html/.htaccess

root@server01.visageweb.com.br [admin]# yum -y reinstall ea-php70-php-tidy.x86_64
