Prestashop - ERROR message when choosing a product (1639646)

Hello Sirs I have a problem in my Prestashop webshop. I get an error message when I click on a product. Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 24 bytes) in /mounted-storage/home122c/sub009/sc67672-MKDX/*****.com/classes/[login to view URL] on line 96 I have added that on my .htaccess file php_value memory_limit 100M and it worked, but it take too long time to load the page, so idont want to use that rule. i need to repair something to let the products work normally without to have to add some changes, just repair them. The probleme happened after while i have imported about 10.000 products and after i have modified some of them. After i have changed some setting on each product i got that fatal error message. I believe that if you want to solve this problem, then you should have experience to PrestaShop. I use Prestashop 1.3.7 write to me and i will write more informaion Thank you in advance.
