Cannot save changes when configuring Anywhere Sliders

Hi,

I'm using the Electronics theme (Nop v2.6) and the Nop Anywhere Sliders plugin has been installed. But when I try to configure the slider(in Admin -> Plugins -> Nop Anywhere Sliders -> Manage Sliders), I get the following error when I hit the 'Save' or 'Save and Continue' button:

Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Could you please help me configure the sliders? Even info about which tables to update in the database will be highly appreciated.

Kind Regards,
Amita

Hi amita,

Try to create new slider again and when you get the error, go to your log and see what error is the last error in it. Please post the error to here, so that we can fix your problem. Also you can send us an email on support(at)nop-templates.com with your website and administration credentials.

Best regards.

Hi Ivan,

Here's the error message when I clicked on the 'Save' button:

Hi Ivan,

I also get this error when I click on a Manufacturer in the plugin that selects products by Manufacturer name (Nop Ajax Filters -> Manufacturers filter):

'Loading the page failed'

I was wondering if these two errors are related somehow, and any ideas on how to fix this error?
