jQuery.browser is deprecated

Hey inforexx,

Thanks for giving us admin access.
Your site seems to be using Enfold 4.0 which is already outdated (released feb. 2017).
The issue is fixed on the latest release of Enfold. (please create a backup first before updating the theme).
A temporary solution for this is to install and activate the Enable jQuery Migrate Helper plugin.

Best regards,
Nikko

Hi Jozef,

Enfold 4.0 uses API key to update and check for theme updates however envato has already closed the use of API key in favor of using tokens, To update I would suggest doing the following (make sure to backup your site first):
Login to ThemeForest and download the Enfold theme.
1. Right-click over the downloaded zip file and extract/unzip it.
2. It should generate a new folder, open it and look for the enfold folder
3. Right-click the enfold folder then zip it, here’s a tutorial on how to create a zip file in windows: https://www.howtogeek.com/668409/how-to-zip-and-unzip-files-on-windows-10/ (this should create enfold.zip
4. Log in to WordPress as and Admin.
5. Install and activate a maintenance plugin and put your site in Maintenance mode.
6. Go to Appearance > Themes, switch to a default WordPress theme like TwentyTwenty then delete Enfold.
7. Click on the ADD NEW button.
8. Click on the UPLOAD THEME button.
9. Click BROWSE and choose enfold.zip file
10. Click the INSTALL NOW button and switch to Enfold or your child theme.
11. Remove the maintenance mode then deactivate and remove the maintenance plugin.
Once update is done, generate an envato token and register your theme so you can check for new updates and update it via theme options, check further information on this here: https://kriesi.at/documentation/enfold/theme-registration/
