FAQ Frequently Asked Questions

Which is better, free themes or paid themes?

It depends on your specific needs and budget. Free themes are suitable for beginners, blogs, or simple websites, but they may have limited functionality, poor support, or include promotional links.

Will the original content be lost after I change the theme?

In this case, you should consider choosing a lighter-weight theme that focuses more on performance.
