Error

Hi!

Im using the plugin for some time, without any problem.

Today, suddenly, it starts to log this error, and stop working, crashing all category pages until it is disabled.

We didnt change anything in our site.

Can you help?

Just for the record, it worked after an iis application pool restart.

But I think it should be investigated.

See you.

Hi IvanSlater,

I am pretty sure there must be some good reason for this error.
You can see in the Log on which page this error happened and try to reproduce it.
This could not happen just like that without any modifications on the web site. Are you sure you haven't changed anything i.e adding some new products, changing settings, modified the database etc.
Please let us know if this happens again and if you could reproduce it, so that we can know if there is a real problem with the plugin and investigate it.
