Author, Editor, Contributor Roles Corrupted

All changes to the roles made in place. So URE deactivation/deletion will not restore roles to its initial state.

What did you change at those roles?
1) Install URE plugin back;
2) Return them to the default state manually using URE. Use as the source of the information:

or just look for the same role via URE at the other WordPress installation.
3) there is “Reset” button at the URE. It will restore WordPress roles to its zero state. But double think before click ‘Reset’. If some plugins changed roles, you will lose those changes, and plugins may stop work.

Right now I uninstalled the plugin, So what would you advise me to do? I’m trying to get them to work again.

If URE did correctly what you asked it for – what’s the reason to uninstall it? If you accidentally deleted some text from the text file, will you uninstall the text editor before try to restore the lost text?

If something was incorrect – I wish to know about the details to check, analyse and fix a problem. At least the screenshots of modified roles could be very helpful to estimate what you did with listed roles.

If you do not wish to use URE, you may use any alternative plugin, which allows to edit user roles. Then act according with item 2.

I am basically saying that I want the roles to go back to the way they were prior to installing the plugin. What do I have to do to make them go back?

1st way: As you edited them manually, you may to return them to the state before you edited them, the same manual way. List of capabilities for each role is available from the link I provided above.

2nd way: restore WordPress MySQL database from the fresh backup you made before trying to edit user roles manually. It is possible to restore just 1 record to the wp_options table – read text below.

3rd way: URE creates backup copy record of the existing roles on its 1st call. It is possible to find it at wp_options DB table by its option_name ‘wp_backup_user_roles’. If you change DB prefix replace ‘wp_’ for your own DB prefix. Get roles value from this record and put to the record with option name ‘wp_user_roles’. This backup record is unavailable if you deleted URE via WordPress “Plugins” page, as it was deleted with all other URE data together.
