I am having a problem with my website. The website is powered by Opencart. I sell digital products. Recently I have been getting an error that sometimes shuts my website down, or slows it down dramatically. The issue is with the JQuerry. I haven't touched anything, out of nowhere it started happening. Sometimes it happens and sometimes the site runs smoothly. Its current state is unstable. I need someone who can fix the issue without deleting or altering any of the products I have up on the store. I need this to be taken cared of as soon as possible in a professional manner.
