Starting on October 19, 2021, we will enable single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
To be prepared for this change and to avoid the need to register during your next ticket submission after the change, we encourage you to create an account here before October 19 using the same email address as your current Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account. You will continue to use ZenDesk authentication until we switch over to single-sign-on on October 19th.

    The article propose a strange workaround.

    <Disable the plugin (or Theme) with underscore in its name.>

    How to disable aplugin which the web site depends on?, I had some sites stopped because of that bug, WP toolkit couldn't update some plugins and this isn't the major issue, the real issue WP toolkit deactivated the plugins it couldn't update which the web site depends on and then the site goes into maintenance mode! sudenly I found many web sites on maintenance mode by toolkit because of this bug.

    Hello Fouad Ahmed Fouad

    Thank you for the feedback.

    Indeed, the workaround is about temporarily disabling the plugin in question to update other components.

    According to the information I have, in WordPress Toolkit update (4.8.0) work with components, containing underscores should be improved.

    If new updates are still being blocked for you, consider contacting support.

    Hi,

    Here we are running Plesk Obsidian v18.0.29 and WordPress Toolkit v4.9.1-3857 and this problem still happening!

    We can't upload plugins that have an folder inside with _ and this is only a plesk problem, because if we upload this same plugin direct in wordpress it install perfect!

    Please, fix this problem!

    Hi Ivan,
