Find the unnecessary jQuery files
You can find the HTML that points to a duplicated jQuery file by checking source code of your website. You can use: Ctrl + U keys or right click >> View source code.
The image below shows an example of duplicated jQuery code.
Note: you may need to experiment with which file is best to remove. Please test your site thoroughly after removing any files.
Create the replacement
Go to Components >> NoNumber ReReplacer >> New.
In the next screen, add the code to replace as the image below:
- Include the HTML that loads the duplicated jQuery file
- Leave this area empty
In the Search Areas tab >> Enable in area >> Everywhere.
Refresh your website and check your source code again. You will see an empty space where previously the jQuery file had been loading.
