Hi Nemo1,
thank you for your update.
Yes, I have already checked this out. The mod_rewrite is properly configured on the server.
The point is that the error appears just if the user decide to change the language from Bulgarian (which is the default one) to English and in reverse only at home page. If the user clicks initially somewhere else, anywhere else and then try to change the language the issue never appears...the issue can be re-produced only from the home page.
I am not aware if it is allowed to publish my site here in case you want to check your self - www.mjewels.eu
In case it is forbidden, please just let me know and I will delete the current post.
Cheers,
George
