I just updated the product page version number to show v1.3, but the file I uploaded a few days ago is correct.
This morning I downloaded the product from the website and in the log tab, it shows version 1.3.
Part of your error last time was because you edited the file, but do not modify the file.
If when you start the cBot in cTrader automate it shows version 1.2 then your web browser is caching the download file, try a different PC or web browser, or clear your cache.
