I could still access the admin page to download the plugin and trigger the rollback. Unfortunately, the theme has no support from the developer and probably it is not going to receive a patch for WP 6.8. I followed the re-install steps and everything worked well. Once the installation was finished, I was force-logged out and upon trying to enter the admin area, my password was no longer valid. Small heart attack. (ref. @ndstry had the same issue mentioned in a previous review, it seems there is a hashing logic changed between the versions). Luckily the password reset email was working well and I could reset the admin account. I have also shut down the website (I am hosting it locally with Local) and then the WP version is also shown correctly. Thank you for developing this plugin! ![](https://secure.gravatar.com/avatar/59da62eebc3ff695c779014618391c0de074ef996e907847d41540f0cfe2226f? s=60&d=retro&r=g) ### 󠀁[Affected Login.](https://wordpress.org/support/topic/affected-login/)󠁿 [VJ1I](https://profiles.wordpress.org/ndstry/) 2025 年 5 月 4 日 1 則留言 Unable to log into site after rollback to 6.7.2 from 6.8.1. Password reset failed to send e-mails. Host provider e-mailed a temporary password which effected a successful log in. Website is otherwise OK. Was unaware of inherent rollback complications from 6.8 due to core encryption modifications, as I saw no disclaimer in plugin description. ![](https://secure.gravatar.com/avatar/c668e3a09c9eea7010f84d719614c6e332509d43899c7976269e395b2ce63ff0? s=60&d=retro&r=g) ### 󠀁[Very nice and easy to use](https://wordpress.org/support/topic/very-nice-and-easy-to-use-29/)󠁿 [Duncan](https://profiles.wordpress.org/duncan1967/) 2025 年 5 月 1 日 Used on 6.8.1 to 6.7.2 rollback – very nice and easy. I’d performed a simple file and folder rollback which worked perfectly but the DashBoard still showed the original WordPress version. Yes, could have fixed that easily (I believe) but this plugin just did what I wanted in about a minute, with the correct rollback version now displayed in the Dashboard, too. Thanks :o) ![](https://secure.gravatar.com/avatar/f78f7cded1ad8ded4a6cb633093f3490f712d63bb30c2bdb386f717be391b926? s=60&d=retro&r=g) ### 󠀁[Would not work on my test site](https://wordpress.org/support/topic/would-not-work-on-my-test-site/)󠁿 [takenyahampton](https://profiles.wordpress.org/takenyahampton/) 2024 年 11 月 5 日 2 則留言 I attempted to use it on my test site and it would not rollback to any previous versions. I ended up using another plugin which worked effortlessly.
