Upgrade WordPress site
I am very new to wordpress, so I decided to ask someone to help me with the upgrade of an existing wordpress site. Firstly he upgraded the wordpress itself and then the plugins individually. There are 2 plugins that does not want to upgrade – WooCommerce and SmartSlider3. He wanted to disable the plugins, but when we access the wp-admin area, we get an error message "There has been a critical error on your website."
We can’t rename the woocommerce file on the cpanel, it gives an error message that we need to look in the log files. We’ve tried renaming it with FTP software, but only get ‘access denied’ error. (although we can rename the other plugin folders)
How can we proceed from here to gain access on the wp-admin again and finish the upgrade? Please help?
