Hello,
Uhmmm, just random words like: hello, hi etc.. also names like: esther, jamae etc, only random letters like: asdfghjkl, but also words like: home, index, etc...
To create a page with the name "index" is not good, cause this overwrites the original index.php in the pages directory. Please upload the pages/index.php from the original WB-package to your host.
If you additionaly set the pages dir to the root (in settings of WB) maybe also the index.php in the root of WB is overwritten. If this is the case please restore this file too.
Have you access to your database? If yes, please compare the pages table with the files in your pages directory. For each name in the table there must be an equal file in the pages directory. Please delete all lines in the pages table, where you don't have a file in the pages directory. Background is, when you create a page and you have no write access to the pages dir, the entry in the database table is generated without also generating the needed file in the pages dir.
On some servers setting permissions with ftp to 777 causes that you don't have write permissions. So not even to low also to high settings can be wrong. Ask your hoster, wich permissions you should set with ftp to get write permissions from php scripts.
There are two places where you can set permissions. With your FTP-Client and from the WB-Backend. I strongly recommand to let the permissions in the WB-Backend untouched and only change permissions with your FTP-Client.
Hope this helps
Matthias
