I can't login in wp-admin website

Seems you have an extra slash in that URL. ??

Try https://pro.cashforcarssandiegoca.com/wp-login.php instead.

Yes, i mistaken that.. I tried to research a solution and the issue now is when I log in wp-admin this error will show ‘You do not have sufficient permissions to access this page.’

If you are not using Multisite, access your database via phpMyAdmin (most hosting providers offer this in their control panel), go to the wp_users table and find the row for your user_login . Note the ID of this row. Now, go to the wp_usermeta table and find the wp_capabilities row for your user_id . Set the value of this row to:

a:1:{s:13:"administrator";b:1;}

Hi,

I try to view the wp-users and I have two users and there ID is 1 and 2

Then I go to wp_usermeta / wp_capabilities

user_id : 1
a:1:{s:13:”administrator”;s:1:”1″;}

What do I need to change on this?

You need to do as detailed above, I provided all the steps there.

Here it is broken out into steps:

1. If you are not using Multisite, access your database via phpMyAdmin (most hosting providers offer this in their control panel).

2. Go to the wp_users table and find the row for your user_login . Note the ID of this row. (it could be 1, it could be 2, or maybe even 3, or more, it depends on what user_login your account is)

3. Go to the wp_usermeta table and find the wp_capabilities row for your user_id .

4. Set the value of this row to:

a:1:{s:13:"administrator";b:1;}

Hi,

I’m not using Multisite.

I have open my wp_users table and I see two users with the ID 1 and 2

When I go to wp_capabilities row, I see the same input of what you want

a:1:{s:13:”administrator”;b:1;}

Do I change anything here?

Yes, you need to do step 4 for whichever user_id you want to modify.

Sorry, I misread. In your first example, you listed the end of the capabilities as s:1:"1";} but now it’s b:1;}?

Please double-check, it should be b:1;}

YEah, sorry I think I have changed it. But still the same error.

Hm, I wonder if something else is interfering.

Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).
