The site (BestInkandTOner.com) has been up for months and a problem popped up this weeked (though no work was done on the site). If you choose a brand like Epson and then click the printer list, you can see Canon printers. If I go to the Admin panel and flush the cache, it comes up correctly - one time. Then the next time it will again show the wrong printer list. What is happening and how can I fix it?
