Random 404 error

[jkun]

I was in the middle of importing my new database and about half way down the modules my impex suddenly started giving me a 404 error?

The rest of admincp works fine but it's just impex. I'm not sure what happend.

I was importing a phpbb3 db if that means anything.

Which import module were you on when this happened?

[jkun]

I can't remember exactly but it was the next module after users.

[Steve Machol]

Clear out the imported session and data and try again. Then if it happens again please state which module this was.

Clear out the imported session and data and try again. Then if it happens again please state which module this was.

I'm not sure how to do this. I can't get into impex at all.

[Steve Machol]

You can run '.../impex/help.php' directly in your browser to do that.

Thanks.

It seems the error is caused during 'Import post'.

[Steve Machol]

This may be a server time and/or memory limit. To increase your limits edit your includes/config.php file and add these lines right under the <?php line:

ini_set('memory_limit', -1);
ini_set("max_execution_time", "2880");

Then use a smaller batch number for import posts and try again.

I edited the config file and tried with half the number and the error happened again.

Please make sure that all Impex files are uploaded and that the permissions for the directories are set to 755 and the files to 644.

Then if you still have this problem this may be due to mod_security. Please see this thread for the fix:

All the permissions are correct and i've done the suggestion from the thread you linked.

It's importing the first 575 posts but after that it brings up the error again.

[Steve Machol]

The next step is to ask your host to check the server error logs. Something is causing this and that info should be in the logs.

[jkun]

I just went through the error logs and there's nothing on there. Eeek.

[Steve Machol]

Well the only possibilities are that there is either something wrong with the source data, or it's a server issue. Unfortunately I really don't have any other suggestions,

However in my experience. 'Internal Server Error' means exactly that - it is a server issue. And AFAIK servers should be logging all such errors. If they aren't then there is something wrong with how this server is set up.

Dramatically lower the number of post being imported per page on the next try.
