Desistale a Wordpress plugin that I developed and gave me an error "could not uninstall completely" , I finished uninstalling it manually deleting the files that had remained in the folder. When reinstalling the plugin is now installed by adding "-1" to the name of my plugin in the wordpress plugins directory. Does anyone know how I can solve this ?. Thanks!
In PhpMyAdmin, or with the manager of the DB you prefer:
Try to find the table "wp_options" in it look for the column "option_name" and in that column look for the value "active_plugins".
Once located, it copies for security the string that appears in the "option_value" column.
Once done, replace the value of "option_value" with
a:0:{}
In this way you deactivate all the plugins, being able to re-activate the ones you need and being able to delete the plugin that got stuck.
Very important to keep the chain that you are going to replace first !!
