Hi all, I'm a brand new user, but because it was so hard for me to do the change of URL, I decided to post how I did it in case I forget and have to do it again
So (assuming you have already set up you blog and everything is working and you only want to change the directory), do:
1. Copy /serendipity directory, to whatever name you want it to have, in my case
http://tothefuturewithlove.net/after_the_pink_goat , so /after_the_pink_goat
2. Replace $old_path with $new_path in following files (in my case replace "serendipity/" with "after_the_pink_goat/)":
config_local.inc.php (../include/tpl/)
create.release.sh (../bundled-libs/)
3. With the help of phpMyAdmin do:
3.1. Export your old database:
In my case, all the options were selected everywhere on the page,export options is set to "sql", the compatibility option was set to "mysql" and everything else was unchanged. Click export.
3.2. Edit the file replacing as above "$old_path" with "$new_path" everywhere. Save
3.3. Create a new database and add a user to it - the same as for the old database would be fine, I guess.
3.3. Import the saved file to a new database - select the file you edited, and set compatibility to "mysql". Hit Import.
4. Go to the new directory, and edit "serendipity_config_local.inc.php" where 'dbName' should be set to the name of the new database.
5. Check the paths in Configuration menu of your admin screen. They should be set to your new directory.
Now it should be working. At least it did for me.
Sorry if I repeat someone, but google didn't give me an answer how to change the URL and set everything again, so this was my way. Have a great day, everyone!
P.S. Of course, I don't guarantee this is the best or even the right way to do this. It's just the only way I know for now. So use it on your own risk.
