Hey there,
May i know what extension/plugin you install recently? Because it seems like some where injected extra <script> tag on the site, you can check my attached screenshot below.
For now I have temporary comment out one line of code from this file JoomalFolder/plugins/system/conversekit/templates/default.php , it should work fine now.
But i would like to check who render this extra <script> tag on the conversekit script there, I found out it seems like your current template render this because when i switch to protostar template, it seems work fine.
Is it possible send us your current template installer to us so I can try investigate this in my locally and guide us some of the sample step to setup this template.
