Astrid Pro updated, now get fatal error trying to access WordPress

I updated Astrid Pro via WordPress and now get this fatal error when trying to login to my WordPress account:

Fatal error: Call to undefined function register_setting() in /home/content/t/i/m/times2studio/html/wp/wp-content/plugins/astrid-pro/updates.php on line 58

I’ve looked at the code, line 58 - could it have something to do with needing to update the license key? If so, how would I do this? Thank you!

Hello Amy,

Can you please try to manually reinstall Astrid Pro plugin? You can learn how to do it here:
https://codex.wordpress.org/Managing_Plugins

Please remember about importance of regular full site backups. And please let me know if you need more help.

Kind Regards, Roman.

Thank you! How do I find and download the latest version of the plugin so I can manually reinstall it? The link in my purchase receipt says it is expired but it hasn’t been a year since purchase yet.

Hello Amy,

Please try to do the following in order to download it. Make sure that you are logged in to aThemes.com, click on MY ACCOUNT link in the main menu, click DOWNLOADS and find Astrid Pro.

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.

Thank you - I was overlooking it before!

I installed Astrid-pro manually in my plugins folder but I’m still getting the same error when I try to login to my wordpress dashboard:
Fatal error: Call to undefined function register_setting() in /home/content/t/i/m/times2studio/html/wp/wp-content/plugins/astrid-pro/updates.php on line 58

Is there something else I should try? Thank you!

Now Astrid / Astrid Pro don’t seem to be loading at all - my site went back to base theme.

Any ideas would be most appreciated. Thank you!

Hello Amy,

Can you please try to reinstall WordPress? But please make a full site backup first. You can reinstall WordPress in one click in Dashboard → Updates section.

Kind Regards, Roman.

Hi Roman,

Thank you. How do I go about reinstalling WordPress when I can’t access the Dashboard?

Best,
Amy

Well, in this case you can manually reinstall it, this tutorial might be helpful:

However, this is not very easy task, so you might want to hire someone for this kind of service, for example find a reputable freelancer on Upwork.

Kind Regards, Roman.

Thank you, Roman. Do you believe there was a hack or can this happen for other reasons?

I’m not sure why it happened, but I think that hack is very possible.

Kind Regards, Roman.
