Option FollowSymlinks not allowed here
Chances are you’re on Virtualmin.
Any Virtualmin site that uses FollowSymLinks can be exploited to allow that user to read all files in /home. That was creating a nightmare
Virtualmin adds some Options as part of a security fix that could otherwise cause all your websites to be compromised if one of them gets hacked. FollowSymlinks gets replaced with SymLinksifOwnerMatch
You’ll need to edit the .htaccess file for your opencart store and replace
1Options +FollowSymlinks
with
1Options +SymLinksifOwnerMatch
You can update all .htaccess files for your sites with
1find /home -name ".htaccess" -type f -exec sed -i 's/FollowSymLinks/SymLinksIfOwnerMatch/g' {} ";"
Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
chances are that rewrite module for Apache is disabled. You can enable it with the following command
1sudo a2enmod rewrite
2sudo service apache2 restart
PHP Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/blah/public_html/system/database/mysql.php:6
mysql_connect() is deprecated now. Older versions of OpenCart used it (1.5.6), but it was updated later on. mysqli_connect() is the replacement. You need to use a driver other than MySQL driver (PDO, MySQLi) to get rid of the error
Update BOTH config.php (config.php and admin/config.php) files line to:
1define('DB_DRIVER', 'mysqli');
PHP Fatal error: Uncaught Error: Call to undefined method mysqli::escape()
make sure the MySQLi extension for PHP is installed and enabled link
1# sudo apt-get install php5-mysql # for PHP5, deprecated
2sudo apt-get install php-mysql
By Default MySQLi extension is disable in PHP 7. To enable, edit php.ini (Apache2, PHP 7, Ubuntu environment)
1nano /etc/php/7.0/apache2/php.ini
and add this line
1extension=php_mysqli.so
mod_fcgid: stderr: PHP Parse error: syntax error, unexpected 'else' (T_ELSE), expecting function (T_FUNCTION) in /home/blah/public_html/system/database/mysqli.php on line 54
then this means you’re probably using OC 1.5.6x? The developer made some changes that broke mysqli. You can get newer versions (get the next closest version from your current install) of system/database/mysqli.php & system/library/db.php (get both, one depends on the other) and replace the old ones link
Check your opencart version by viewing the index.php file, you’ll get something like
1define('VERSION', '1.5.6');
Now download the files for the next release of OpenCart from the official site’s downloads section (in this case got 1.5.6.1)
PHP Fatal error: Uncaught Error: Call to undefined function mcrypt_create_iv()
Make sure mcrypt module is installed
1sudo apt-get install mcrypt php7.0-mcrypt
Restart Apache afterwards
1sudo service apache2 restart
PHP Fatal error: require_once(): Failed opening required '/system/startup.php' (include_path='.:/usr/share/php:/usr/share/pear') in index.php on line 23
Check your server paths in config.php and admin/config.php.
This error can happen after you have transferred your opencart site and the paths may have changed (for example, when moving from cpanel /home/user/site to barebones/webmin based server /var/www/site)

Your log and cache folders are not writable anymore. source Double check your permissions
1# chown -R www-data:www-data /var/www
2chmod 777 system/logs/ -R
3chmod 777 system/cache/ -R
Different opencart versions have different opencart folder structure
1rm -rf /home/MYSITE/public_html/vqmod/vqcache/*
