Ok, this is my fourth attempt. Thought I'd cracked it on the third attempt but it seems everything has gone down again!
I wanted to install wordpress on our streamline.net account (on the sub domain susanne.treacletheatre.co.uk) - set up the database, loaded up the files, followed all the instructions, etc.
2 days ago it was working fine (for one session, in which I uploaded some initial themes, put in the user settings, changed the password, tested to see if the site was where I wanted it (it was), and had a general browse). I tried again today. Nothing, just the usual:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, firstname.lastname@example.org 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.
Hmmm? This is the second time this happened (after the first problem I started from scratch), so I guess it is something wrong with my upload or the FTP manager (checked and all the files were there). I have tried everything on http://codex.wordpress.org/Login_Trouble apart from the scary editing stuff in PHPmyAdmin.
Only other note that may be relevant is that I moved the index.php into the main ht-docs folder, leaving the rest in the wordpress folder. rerouted it though and this was all before it 'worked' for an initial login.
Any help really appreciated. Let me know if i can provide any extra info...
