Topic: 403 error when refered from Search Engine

[ferzam]

Hi, I have gone through all 403 errors in this forum and I cannot find the solution for my issue.

Here's the thing:
- I have my site www.mysite.com which redirects to www.mysite.com/portal
. I have Mibew installed on www.mysite.com/mibew
- I have the button for login into mibew and I have put it into index page.
- if I enter manually the URL on the browser www.mysite.com I can click on the Mibew button without any issue.
- If I search on google "mysite" then my website is the first one displayed into search results.
- I click on the link within Google and my site is displayed.
- Upon clicking on  Mibew button I get 403 Error.

I have permissions of 755 in all files and folders

Is there any condition I should put into .htaccess file or something?  Permissions missing?
When I click like this the URL has the following value.

http://www.mysite.com/mibew/client.php?locale=sp&url=http%3A//www.mysite.com/portal/&referrer=http%3A//www.google.com.mx/url%3Fsa%3Dt%26rct%3Dj%26q%3D%26esrc%3Ds%26frm%3D1%26source%3Dweb%26cd%3D1%26ved%3D0CCoQFjAA%26url%3Dhttp%253A%252F%252Fwww.mysite.com%252Fportal%252F%26ei%3DfzdTUuqXBYyO9AS-joC4BA%26usg%3DAFQjCNH-2if81sEm63q_MmLd9tksSQzboA%26bvm%3Dbv.53537100%2Cd.eWU

Mibew Messenger doesn't throw away 403 errors at all. Maybe the key to your problem lies somewhere in your redirection rules? Could you post it here?
