AJAX and PHP error

Hello,

Since the last updates I am presenting the following problems:

– With the AJAX price preload active, the prices are not finished showing on the web. It stays charging and doesn’t show.

– It generates PHP compatibility errors with other plugins (Loco Translate).

If you could help me, I would appreciate it.

Thanks.
