Cannot access plugin page only – Briefly unavailable for scheduled maintenance

Hi, I just went to auto update 3 plugins, like I always do and I accidentally clicked another link on the screen which aborted the upgrade.

The whole site was stuck in ‘maintenance mode’ so I removed the .maintenance file like I have read to.

This fixed everything BUT the plugins page….

Whenever I click the plugin page in admin at https://drumtrip.co.uk/wp-admin/plugins.php I still get the message ‘Briefly unavailable for scheduled maintenance. Check back in a minute.’.

I have even updated the 3 plugins manually using FTP after they failed on auto and it has not fixed the issue.

How can I access the plugin page again on my site?
