Hello Ziaul Kabir... thank you very much.
Now the site work well.
Could I find out what happened?
I am always very careful—when using templates that come with the Easy Store component built-in (whether free or paid)—not to update that component. I say this because I previously tried updating it in other templates with Easy Store integrated, and problems arose.
Now, I make sure not to update or alter anything related to Easy Store (except, of course, for product images and content).
Could you tell me why this happened? I am using the Mega Deal II and Allura examples to showcase them to clients, and I want to know exactly what I should not touch. I only update SP Page Builder and Joomla 6.x—not Easy Store—yet I’ve still run into issues.
Thanks!!...
