thanks for using our modules
I am using a vps with 1 gb ram. I increased to 800 mb, now I get Fatal error: Allowed memory size of 838860800 bytes exhausted (tried to allocate 523800 bytes) in /home/hdavy2002/domains/shoppersmall.in/public_html/classes/Configuration.php on line 316
that is weird, usually you should not need so much ram. I guess there might be some data integrity issue of something.
1. are you sure it works without error before install our modules and if you unihstall our module?
2. are you using any other 3rd party modules? you may try to uninstall them to see if the error disappear (to identify the cause)
3. can you check if you define product categories in a way of loop?
