Symptoms
- An attempt to update the Rank Math SEO PRO plugin via the WP Toolkit in Plesk causes all other WordPress plugins for the website to become disabled
Cause
This behavior is caused by a known WP Toolkit bug with ID #EXTWPTOOLK-8487, which is planned to be fixed in one of the next WP Toolkit release versions.
You may track the bug resolution in the Change Log for Plesk Obsidian
Resolution
Until the bug is fixed permanently, you may apply the following workaround:
Disable the Autoupdate option for the Rank Math SEO PRO plugin for the affected website via the WP Toolkit in Plesk (only for the WP instances that do not possess an active and valid license for this plugin) by following these steps:
2. Go to WordPress > example.com > Plugins tab
3. Find the Rank Math SEO PRO plugin and move the Autupdate slider for it to the left (disabled position)
Comments
Curious is there any updates regarding to this issue. We still experiencing the problem.
Rank Math SEO 1.0.269
Rank Math SEO PRO 3.0.94
We just hit this on current versions and wanted to confirm it's still an active issue.
Environment: Plesk Obsidian 18.0.81 (CentOS 7), WP Toolkit 6.11.7-10909, WordPress 7.0.8/7.1.4, PHP 8.3.36, Rank Math SEO PRO 3.0.124.
On the night of Nov 10-11, 2026, WP Toolkit's nightly auto-update tried to update Rank Math SEO PRO (3.0.124 -> 3.0.125) on four of our sites across three Plesk servers. Our Rank Math subscription had lapsed, so the update failed. Afterwards every other plugin on each site was deactivated.
What we saw on one site before reactivating anything:
- The WP Toolkit log shows "update initiated" and then "update failed ... due to unrecognized reason" for Rank Math SEO PRO, with no deactivation entry.
- active_plugins contained only the two Rank Math plugins, and recently_activated was empty.
- Running the same update from the WordPress Plugins screen fails with a PCLZIP_ERR_BAD_FORMAT error but does NOT deactivate other plugins, so the problem is in WP Toolkit's update path.
The workaround in the article (turn off Autoupdate for Rank Math SEO PRO) works, but autoupdate is on by default for newly installed plugins, so it's easy to miss. Can Plesk confirm which WP Toolkit version fixes EXTWPTOOLK-8487? We're also filing a support ticket.
We also confirmed that making sure our Rank Math license was up to date fixed the issue (it had expired due to an unexpectedly cancelled payment method).
