Can’t access WP Admin “Sorry, you are not allowed to access this page”

Thanks so much Arvind, I’ll try that suggestion and thank you for the links. ??

I’ve had the same issue. I’d deactivated all my plugins first (as I’d got the Gutenberg & Advanced Gutenberg) plugins installed. I also had Akeeba Backup installed and I deactivated that.

It turns out that reactivating Akeeba Backup allowed the update to start – by first taking a backup

Perhaps there’s something in the upgrade that insists on taking a backup first?

Further- this has now worked. Akeeba backup took a backup of the site and then the update wen’t ahead properly

Hi Trevor

I’ve reactivated the plugins but perhaps I’ll deactivate all but the backup one and see if I have the same success. Thanks so much for the suggestion and glad to hear yours is resolved ??

Many thanks
Dee ??

Let us know how you get on.

Hi Trevor

Thanks for following up.
Nothing has worked to date unfortunately.
I followed both yours and Arvind’s suggestions and even loaded back to 4.9.8 which I didn’t have any problems with.

The strange thing now is that if I try to login to wp-admin, it takes me to my profile page as if I’m a registered user of the shop. I can access the /my-account page and check orders, account dashboard etc and log out.
Could it be a permissions problem?

No idea, sorry

Hi @trevorwood

Hope you’re well.

It’s taken a while for me to reply sorry, but just thought I’d give you an update.
It turns out that the database somehow corrupted. The only solution was to reinstall from an older backup (5 days prior). I tried just about everything including a fresh install of WP.

Thanks so much for your willingness to help, really appreciate it!

Kind regards
Dee ??

Good to hear that you’ve got it all sorted out now.

I found a solution for the same issue.

For those who are still suffering from the same case and didn’t find the solution:

I’ve dived deep in WP source code and found that in options, the key of the user’s capabilities are stored together with the prefix of the database tables (e.g. prefixhere_capabilities, or wp_capabilities in default case).

So, if you moved your WP install manually (transfer files and database) the solution is:

0.) Open Phpmyadmin
1.) In options table, search for “_capabilites” in option_name column.
2.) Replace the old prefix with the one (oldprefix_capabilites => newprefix_capabilites)
3.) Enjoy! ?? You can now access your WP Admin.

I would publish the mysql UPDATE statement to do the replace, but maybe it would case more problem for those who has another issue.

I hope this will help some.

Cheers,
