Interactive elements stopped working on the site after migration

If, after the transfer, interactive elements on the site stopped working (for example, buttons are not pressed), the most likely cause of this problem may be damage to the content of JavaScript files when downloading / loading the site by file using FTPclient, in which the binary data transfer mode is disabled. As a rule, the problem is accompanied by the presence of various errors in the browser console related to the operation of JavaScipt (for example, syntax errors).

To remedy the situation, download / upload the site files again, having previously included in FTP- client forced binary data transfer mode (instructions: FileZilla, Total Commander). Alternatively, you can download / upload site files as an archive and unpack it using filemanager, which will also exclude the possibility of damage to the contents of the files.
