Question: I am having the strangest problem ... every time i commit i get and error like this:

```
commit failed (details follow): MERGE of '/svn/project/trunk/web/directory/': 200 OK (http://mydomain.com)

```

that is the directory of the file i modified.

**Later Edit**
i have web dav SVN installed and i commit to a HTTP URL.
and there is a post commit hook doing a svn update on a directory on the same machine

Any ideas ?
thank you for your help.

Answer: 
You'll get that error if your post-commit is failing. Try running it from the command line with the same args to make sure it works properly. I had this error a week or two ago when my python script was erroring out.
Below steps works with me

1. execute the program called 'TortoiseSVN Repository Browser' in your computer.
2. It prompts the certificate was failed, and asks me to log in and restore the certificate
3. After log in, everything was fine
