im using alot of YITH pkugins
Many Yith products are premium/paid products not supported in these forums; you need to go to the site where you purchased them for support.
the guy who help me do my website installed them about 1.5 years ago.

is there a way to go to regular plugins?
That’s your call; there are many free e-commerce plugins and addons for Woocommerce, etc: https://wordpress.org/plugins/search.php?q=ecommerce
The complexity to replace them all depends on your site. If you can’t do the work yourself, consider looking for a reputable person on http://jobs.wordpress.net/ or http://directory.codepoet.com or http://upwork.com
(FYI, it’s not a good idea to respond to work offers from random forum users who have read about your issues.)
