What browser do you use?

Firefox

Thanks.
From other user report I understood already that it is not a browsers compatibility issue. Please let me know what WordPress localization/language files you work with? For this moment I can not reproduce the problem, as plugin work fine as under my local test environment, as on shinephp.com site.
If you have test environment where such error occur and may let me have access to admin dashboard there it will help to isolate the problem.

I have no test site just my working site. I use plain wordpress3 and not sure what language localisation things you mean…the ones that came with wordpress3.

Now though I am having even more serious errors but not to do with your plugin so I will have to wait until that is fixed before worrying further about this one.

Thank you for your time.

I congratulate you with succesful resolving your page redirect problem.
Under localization I meant the base language for your WordPress installation. Do you use default English WordPress installation or any different language for your admin back-end?
