If you're certain that the tracking script has been correctly installed, saved, and published on your site, yet it's not functioning as expected, a common issue could be the use of incorrect quotation marks in the script code.

Interestingly, there are two types of quotation marks: 'straight' marks and ‘curly’ marks. For coding purposes, browsers require the use of straight marks (also known as 'typewriter' quotation marks). Curly quotation marks, while visually appealing in text documents, are not recognized by browsers in the same way. If your script contains curly quotation marks, they might look correct visually, but your browser will not interpret them correctly, preventing the tracking script from executing properly.

Ensure that your script uses straight quotation marks to avoid such issues and ensure smooth operation.
