Your Plugin from RegularLabs is not compatible.

The Upgrade did not finish and all changes in the database structure have not been executed

OKAY thanks! I renamed that folder and got access to the backend but there is no extension manager. I got: dashboard content menus components users system. Quite a few errors on back and the front is:
Call to undefined method Joomla\CMS\Application\SiteApplication::isAdmin()

[nacc]

See https://www.google.com/search?q=isAdmin%28%29+Joomla

[Per Yngve Berg]

Enable Debug and get the Stack trace ti be able to identify the plugin that uses this J3 call.

Lots of acymailing errors:

maybe i will try to contact acymailing

[gws]

Suggest you read https://www.acymailing.com/acymailing-s ... 90-v8-5-0/

[lip420]

thanks
i was going to try to install the newer version of it from cpanel if possible do you know how to do that?

[gws]

joomla cpanel or server cpanel?

[lip420]

I am not sure that will work. I changed all the names of the acymailing folders in modules components and plugins and the errors still show. You would just upload it into the compnents folder or where?

[gws]

install it like any other joomla extension. As Acymailing was hacked you might have to uninstall the original first then install the update. I don't use it so i don't know.

[lip420]

You can't access extensions

[ceford]

Looks like the upgrade was a disaster. I think you need to go back to your last Joomla 3 Backup. Read carefully the information on upgrading: https://docs.joomla.org/Joomla_3.x_to_4 ... _Migration. Run the Forum Post Assistant and post the results here so your installtion settings can be checked.

[nacc]

@lip420: Please see what I wrote earlier for the solution:

See https://www.google.com/search?q=isAdmin%28%29+Joomla

[lip420]

See what you wrote where? you keep linking to a search results page and if it was that first result your name isn't on that page.

[nacc]

Did you look at the results from the Google search? The Google search results show that other people have had this isAdmin() error and how they fixed their problem so that they could login to the backend of their websites.

[lip420]

I tried upgrading and didn't go well so and didn't complete so i was thinking of trying to do it from cpanel i've got: Joomla_4.3.4-Stable-Update_Package

can i just do this in cpanel to public html?

[Per Yngve Berg]

The only upgrade possible is to use the Joomla Update Component.

Disable the extensions
breaking the Upgrade and try again.

[lip420]

I don't see how i can do that as there is no joomla update component on backend now

[Per Yngve Berg]

Restore your backup of J3.

[lip420]

Don't have the files just a db backup. I tried going to phpmyadmin and disabling the acymailing extension but it didn't seem to do anything.

I RENamed regacymailing.php-OFF and now have a site.

I RENamed regacymailing.php-OFF and now have a site but there is still no menu for extensions on backend.

Yes it is but its not nacc.

If you disabled any problem extensions (apparently the acymailing), are you logging in as a super administrator? That should be the same log in as you used for J3. Are you getting any menus at all, or a blank side bar in J4? The image in your original question seems to be missing.

If you have an export MySQL file for the J3 database, you can restore J3; drop the J4 tables and import the J3 SQL file. You will also need to re-upload the J3 files (of the version you were using) and possibly reinstall all the extensions you were using in J3. (The data should still be there created by such extensions).

When you get the J3 site working our advice would be, to install Akeeba Backup immediately and then take a backup with that, and copy the JPA archive to a safe place.
