i had a problem wth php.It display error like below. It work well in other computer, but when i tried to run it in another computer it display error like below. I think i had a problem with my wampserver 2.0 configuration.
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.Please contact the server administrator, webmaster@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.More information about this error may be available in the server error log.
Its due to mod_rewrite. WAMP had commented this option by default.
You need to go to WAMP icon in notification area, Apache, httpd.config
search for mod_rewrite, and uncomment it.
After that RESTART WAMP AND YOU ARE DONE!
This is because mod_rewrite module is disabled in your Apache's configuration:
If your website is hosted at local machine you can simply open httpd.conf in Apaches's conf folder and search for "mod_rewrite". If mod_rewrite line is having a # in front of it, just remove this #, save file, and restart Apache.
If your website is hosted at shared hosting server then you may not have privileges to make changes in Apache's configuration. So you have to ask your hosting administrator to enable mod_rewrite module for you. This is already enabled by almost every shared hosting provider.
This is mod_rewrite problem, just enable mod_rewrite in your apache server or tell your website hosting company to enable it for you. This will make your site work.
Although everyone says the same, I want to add the answer based on some information I collected from this site.
This kind of error is happened if apache mod_rewrite feature of your server is not enabled. By default WAMP server does not load this Apache Mod Rewrite module. It is disabled by default. You have to enable a this option to load this module. There is line in WAMP Apache configuration file about this but that is commented by default. To enable this mod_rewrite feature follow this instruction.
- Look at Wamp icon in notification area on system tray (near Clock in Windows OS)
- Click on the WAMP icon
- Go to Apache>httpd.config
- A Configuration file will be opened in “Note Pad” or your default text editor.
- Search the text “mod_rewrite” , you will find a line “#LoadModule rewrite_module modules/mod_rewrite.so“
- Uncomment this line by removing the Hash “#” from the beginning of the line.
- Save the file Restart WAMP Server by clicking “Restart All Services” from WAMP menu. YOU ARE DONE!
Check the Wampserver log files, this issue is related to something in your Apache configuration.
Definitely do what hunzaboy suggests first. Then if you're still getting the error, I found that one of my directives in my httpd-vhosts.conf file was causing the same error to persist even after taking his advice. I commented the line: "Require all granted" (which worked using a newer version of Apache) and everything was fine.
this must be commented in: LoadModule rewrite_module modules/mod_rewrite.so
For anyone finding this question, and mod_rewrite is ALREADY enabled...
Check that WAMP hasn't put an unwanted .htaccess file in the root of the C:\ drive.
This happened to me, I think after experimenting with different settings in the httpd.conf file.
After I'd reverted my httpd.conf settings I started seeing the Internal Server Error. Deleting the .htaccess file fixed the problem.
I had this problem but the rewrite module was already enabled. There is a header command in the shops .htaccess file that was causing it. Enabling the headers_module in apache fixed it. Thought this might help someone.
