Hello Guys
I am having this issue for past few hours that whenever I try to add some changes in my forum codding, it gives me permission error message. For example when I try to page to navigation menu  or try to add an advertisement code it gives me again and again this message;
''You don't have permission to access /xxxx/index.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request''.

xxx is the example of my admin directory. I have changed its name from admin to a different. 
Earlier to this problem I have the issue of login. For example when I login to my dashboard I would not be able to click on any option on dashboard because doing so would log me out automatically. Fortunately that issue has been solved a few hours ago but now this one started.
My forum is www.iiustudents.com
My last thread regarding login issue was  https://community.mybb.com/thread-213560.html 
My another thread regarding navigation menu is   https://community.mybb.com/thread-213546.html
Please help me because my forum has made me tired because of these one or another issues.
Thanks in advance.

A 403 Forbidden error means that you do not have permission to view the requested file or resource. While sometimes this is intentional, other times it is due to misconfigured permissions. The top reasons for this error are permissions or .htaccess error.


Do you have any plugins because this might be causing a problem try disabling them by going to

Admin CP -> Configurations -> General Configurations -> Disable All Plugins (Yes)

If that doesn’t work please make sure you have mod_security disabled. You might need to contact your web host. Also please try it on a different connection.

Since I noticed from your old post you use MyBB 1.6 please see the links below.

Wow
You are great. It worked. By disabling mod_security it worked. I successfully add my page. You can check it at www.iiustudents.com
Now I have a few simple questions.
Should I enable mod_security after making these changes or left it as it is?
After enabling_security will it affect my these changes?
Should I repeat this process every time when I want to make some changes?
Thanks in advance
