Error MEssage 500 coming || I have changd the host

Hi,
I have purchased a blog. The seller offered me the full back up and mysql database. I have very poor knowledge in these technical things. What I have done so far-

Step 1: Uploaded the back up.gz file from file manager
Step 2: Extracted the file in the public_html directory
Step 3: Uploaded the mysql file from phpMyadmin

But it is showing 500 error message. Could you please tell me the reason and what I should do with that back up file. I do not know all these stuffs.

Any help or response is welcome.
Thanks

 

You will need to edit the wp-config.php file in the WP install directory. Inside of that file will be your database login credentials.

Additionally, you may have to go into phpMyAdmin and edit two entries inside the wp_options table (wp_ is the default extension, yours may be somthing else like xxx_options). Look for the two options in the option_name field with a value of siteurl and home, and change the root url of those entries to match your domain. If there is a folder attached to either entry, leave that appended to the end of your root domain.

I am really confused. I have not done all these things before and it is really hard to debug.

 

Just check your files... which you have uploaded in file manager or your FTP - do first download the file ".htaccess" and then delete this file... but first dont forget to download it to your computer...

i do think problem will be solved once you delete this .htaccess file

Hope this helps...

 

Are you saying that you have transferred a WordPress installation from one server to another in the past? Or what? What part is confusing?
