PHP Fatal error on WP_Rollback_API_Fetcher

I get a similar error when Plesk tries to update the plugin:

 Updates were not installed for the following items:

1. Website “My Website” (https://mywebsite.com): Failed to reset cache for the instance #1: PHP Fatal error: Cannot declare class WP_Rollback_API_Fetcher, because the name is already in use in /var/www/vhosts/mywebsite/website/wp-content/plugins/wp-rollback/src/class-rollback-api-requests.php?on line 2

Hey @applina @wykananda – thanks for reporting. I’ve seen reports of this and will investigate. I have created an issue here: https://github.com/DevinWalker/wp-rollback/issues/88

Thanks for reporting. I’ll report back with more information or a fix. Hopefully a fix ??

Hey?@applina?@wykananda?– me again! I have a Plesk site with WordPress installed on it and have been trying to reproduce this issue, but without any success if seeing the Fatal Error you both describe. Can you provide me any more detail, such as PHP version, Plesk configuration, etc?

I am somewhat familiar with Plesk, but not an expert. Any help is appreciated!
