Thank you for all suggestions. In the latest version (2.0.5.6.4 which soon be available in the stores) we have solved the following problems:
1. Added auto redirect to SEO Aliases. For example, if is configured the alias:
http://v2.ocdemo.eu/desktops/?mfp=manufacturers[apple,ASUS,dell] -> http://v2.ocdemo.eu/desktops/test-mfp-seo
and the customer will open directly: http://v2.ocdemo.eu/desktops/?mfp=manufacturers[apple,ASUS,dell] will be automatically redirect to: http://v2.ocdemo.eu/desktops/test-mfp-seo
To activate this option please go to MFP -> SEO -> SEO Settings -> and turn on "Auto redirect to SEO Aliases"
2. Added auto redirect to URL with or without slash at the end of URLs (depends of the settings in MFP -> SEO -> SEO Settings)
3.
Problem has been resolved. Now isn't possible to open: http://v2.ocdemo.eu/desktops/test-mfp-seo in another categories. For example, if you will try to open: http://v2.ocdemo.eu/desktops/pc/test-mfp-seo you will see error 404
If someone has any another suggestions about SEO, please let us know - we'll try to introduce them as soon as possible. We would be grateful if you could describe the problem in English.
