Yes, I would remove that file so that the plugin is completely removed.

Generally, one should disable any caching plugins or services while actively working on the site.

As for the last point, one should always have the latest updates applied 🙂

However, make sure to have good backups of both the site files AND the database before doing so.

At this point, I would suggest renaming the wp-plugins folder to disable all plugins. Once you are able to log in again, you can then reactivate them one by one to test which one is causing the issue.

Although the cache plugin may have something to do with this, the error you show is in your theme’s function.php file. And it is the very customizable Divi theme from Elegant Themes, which you may also have worked with when adding the cache plugin 🙂

If you still have the default TwentyFifteen theme installed, use your GD cPanel phpMyAdmin to change the template and stylesheet fields in the wp_options table to twentyfifteen If it is theme-related, this should get the site back and allow you to log in.

@ayeshapunu – good to hear that your original question was resolved 🙂

Could you please mark this topic as resolved and post your new question in a new topic, as it makes things easier for others who may be searching for a similar problem 🙂

As you are not able to log in to make the change, one of the quickest ways it to do it via the database: change the siteurl and home fields in the wp_options table to:

http://mainsite.com/wordpress

This will then let you log in at http://mainsite.com/wordpress/wp-admin or http://mainsite.com/wordpress/wp-login.php

Once logged in, install and run this plugin to update the rest of the URLs:

http://wordpress.org/plugins/velvet-blues-update-urls/

— select all options EXCEPT the last one (GUID)

Once that is done, go to:

Settings > Permalinks and Save.

I’ve tried the raw and generated passwords from the wp_users password
database variable in the wp-config file and neither work

The values in the wp_user table are for the WordPress login, and NOT for the database 🙂

Given the name of the database is wordpress, this is what your wp-config should look like:

/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'root');

/** MySQL database password */
define('DB_PASSWORD', '');

/** MySQL hostname */
define('DB_HOST', 'localhost');

A couple things:

– is the WAMP system tray icon ‘green’

– are you able to successfully see the WAMP start page when you enter http://localhost
