Hi there,

EE3 and EE4 are vastly different systems.

When you activated EE4, you should have seen the option to migrate your EE3 data to EE4. Did you run through the migrations?

When you activate you’ll see something like this – http://take.ms/OWjyr

Clicking on the link to view maintenance mode shows the option to Migrate your date – http://take.ms/iFOsJ

Does that look familiar?

hi tony

No i didnt see this option of it detecting a previous version with option to migrate data? would this be because we set up a new account to purchase the ee4 version?

thanks

No this is not due to using a new account, EE4 should detect if EE3 has previously been installed on your site and offer to migrate the data.

Which version of EE3 did you have installed on the site?

i had 3.1.20.P installed on the site?

Hi,

3.1.20 is quite old. I think there was a minimum need of 3.1.36 required to then migrate to EE4 due to database differences.

If you reactivate EE 3.1.20 do your events reappear?

If they do, it would be advisable to upgrade your EE3 first then swap over to EE4.

Also, did you take a backup of your site before trying the upgrade?

hi yeah if i activate old version the events appear again. how do i upgrade the ee3 version? as we dont have access to the account used to purchase this one, thats why we had to set a new one up to purchase the e44?

thanks

You can updgrade the ee3 version by downloading the current version of EE3 lite and activating. You can download it here.

Then you deactivate ee3.1.20, then activate current ee3 lite. The database update script will run and will make the data migrate-able to EE4.

Then when you go to update to EE4, you’ll need to deactivate EE3 first.

The webpage at http://mydomain.com/wp-admin/admin.php?page=espresso_about has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

Hi, could you deactivate any HTTPS plugins that may be running on your site?

This includes the old Espresso HTTPS plugin which is no longer recommended.

If you are not using any with that name, then a security plugin may also have this feature built-in for switching pages to HTTPS.

Hi there,

Here’s a bit of code you can add to a custom snippets plugin that will disable the redirect to the About page:


// stop redirect to about page after update
add_action( 'init', 'ee_remove_about_ee_redirect', 4 );
function ee_remove_about_ee_redirect() {
    global $pagenow;
    if (
        ! in_array(
            $pagenow,
            array( 'wp-login.php', 'wp-register.php' )
        )
        && class_exists( 'EE_System' )
    ) {
        remove_action(
            'AHEE__EE_System__initialize_last',
            array( EE_System::instance(), 'redirect_to_about_ee' ),
            9
        );
    }
}

Please be sure to activate the snippet plugin before you activate EE4.

infact i never actually clicked activate on that snippet and now that i have i get the white screen of death?

A white screen of death means there’s a PHP error in your code somewhere.

You can check your error log or enable WP_DEBUG to find out what’s causing the white screen of death.

I’m sorry for the trouble. Please try this code instead:


// stop redirect to about page after update
add_action( 'init', 'ee_remove_about_ee_redirect', 4 );
function ee_remove_about_ee_redirect() {
    global $pagenow;
    if (
        ! in_array(
            $pagenow,
            array( 'wp-login.php', 'wp-register.php' )
        )
        && class_exists( 'EE_System' )
    ) {
        remove_action(
            'AHEE__EE_System__initialize_last',
            array( EE_System::instance(), 'redirect_to_about_ee' ),
            9
        );
    }
}

The above will ensure the fatal error isn’t thrown.

When you go to activate EE4 with the above code in place, it may bring you to a white screen, because it’s not redirected to the about page. You can navigate away from the white screen by hitting the back button.

thanks, i can now activate it but in maintenance page its still not giving me option to migrate data from v3 to v4?


Tony

That’s likely because EE4 was activated previously (when EE3 hadn’t been updated)

You haven’t created any Events/Registrations/etc within EE4 yet correct?

If so you first want to create a database backup*, there are many plugins available to do this. Here is one I use – https://wordpress.org/plugins/backupwordpress/

Then go to Event Espresso -> Maintenance -> Reset/Delete Data tab.

Within there you will find the option ‘Permanently Delete All Event Espresso Data’

http://take.ms/E00XK

If you click that it will reset the EE4 tables as if EE4 had never been activated. Then when you re-activate EE4 again, the migrations should trigger.

*Note as that function deletes tables from the database, it is highly recommended to create a database backup before hand and not skipping this step, we’ve not had reports of issues with the feature but it is better to be safe.
