Cannot login and cannot edit text boxes on website

Hey Caitlin Canger,
Thanks for the login, you site is very old 3.7.1 this is not comparable with the WordPress 6.4.1 that you are using.
The latest version is 5.6.8 so you need to update. You will only be able to manually update, so I recommend making a full site & database backup using your webhost backup tool, ask your webhost to help if you have not done this before, typically a webhost will make a automatic backup each month but you should ask.
Then deactivate all of your plugins, and the follow these steps:
To update your version of Enfold you will need to download the latest installable WP version from your Theme Forest account and upload it to your WordPress ▸ Appearance ▸ Themes ▸ Add Themes ▸ Add New

after you choose the zip file and click install, you will see a This theme is already installed message because you are updating, you can continue

then you will see the Theme updated successfully message.

I don’t expect that you will have any problems with the update as I have seen sites this old update fine. But I see that you are not using a child theme, which is fine, but if your theme has any customized files the customization will be lost, not any theme settings just if you or a developer make any special code customization. You probably didn’t but you should know so you could save those files if you did.
After you update and check your site you should activate your plugins one at a time and look for conflicts, I don’t expect any but if you have old plugins it is possible.

Best regards,
Mike
