Trac detected an internal error: AttributeError: ‘NoneType’ object has no attribute ‘replace’

I was trying to fix the error from the title for a few months now.

It was about using tracdownloader plugin from: http://trac-hacks.org/wiki/TracDownloaderPlugin

I have applied the patch it worked, but it stopped.
I have tried almost everything, like other linux distro or python2.5 or python2.6.

My mistake was in trac.db, the default sqlite database of trac.

When I finally decided to manually import the tables from the old database into a new one: downloader_category, downloader_downloaded, downloader_downloaded, downloader_release.
When I had to import downloader_release tables rows I have noticed that the last one from the dump is:

INSERT INTO downloader_file VALUES(19,7,NULL,NULL,NULL,NULL,1261067753.63897,NULL);

I have no ideea how that row was added there, but, after removing that one from the original database tracdownloader start to work again.

So, next time you encounter this error verify you code to be correct, and after that, the database.

XP Error Code : 0×80090006

Suddenly this error appeared: “A problem is preventing Window from accurately checking the license for this computer. Error Code : 0×80090006″.

I have no idea why.

According to others what you can do one the followin:

• Log into safe mode and re-register a couple of dlls:
  regsvr32 regwizc.dll
  regsvr32 licdll.dll
• Fix C drive association by using regedit32:
  See KB914232
• Reinstall or repair.

For only the third worked.

You can backup files by using Safe mode.

Remember,  backup your data often.

Later edit:

You should verify your XP license or for viruses/rootkits or, more general, malware.

Fix drupal installation

After you have filled the database name, user and pass nothing happens, the site wont go further to install the pages, but you have this kind of error in your apache error.log:

Call to undefined function user_access() in /var/www/html/.../includes/theme.inc

The solution is to download drupal directly on the server or to archive the files and upload them to the server as a single file.

This worked for me, hope this will help you.

apache + mod_ssl, 12263 error

Recently I wanted to enable https on a opensuse 10.2 server. After generating certificates using easy-rsa from openvpn package, and installing them in apache’s config I got an 12263 error in firefox.

Searching logs didn’t help: only messages about “Invalid method in request \x16\x03\x01“.

Googling for about 30-40 minutes didn’t help but i have found the following link:

http://en.opensuse.org/Apache_Howto_SSL

where, at the end of the page says:

to check your vhost setup, use "httpd2 -S -DSSL"

Cause: client speaks HTTPS, server speaks HTTP. If that happens to be port 443, it means that the server is listening on the port but not with SSL.

I went in apache’s config from sysconfig (/etc/sysconfig/apache2) and I have added “SSL” like below:

APACHE_SERVER_FLAGS="SSL"

and it worked .
