[Plugin: FG Joomla to WordPress] Failed to open stream

Did you turn on the PHP directive “Allow URL fopen” in php.ini ?
Are your images accessible from another domain ?

If this still doesn’t work, give me your Joomla site URL and I will make a try.

I also note that in both cases, a file that I uploaded through the normal WordPress mechanism did not actually get deleted, even though it was deleted from the Media Library list in WordPress.

Yes, that is true. The physical media files are not deleted. Only the reference in WordPress is removed. If you run the import again, the media files are overwritten.

I notice that in the error message, the target destination is given in terms of the server’s file system, and not in terms of target URL. Is that correct?

Correct. The source is an URL and the target is a file on the server’s file system.

Yes, Allow URL fopen is on.

The site is https://www.kbs.msu.edu but I made a copy of it at oldweb.kbs.msu.edu where I could make sure it was on. I just now removed the IP address restrictions on oldweb.kbs.msu.edu so you could access it. However, I would not be able to give the mysql password for that site; if you need something like that I’d have to set up a dummy web to do it with.

The full error messages are like this, btw:

[fgj2wp] Can’t copy oldweb.kbs.msu.edu/images/stories/Sanctuary/News_Item_Photos/goslings.jpg to E:\webhosts\newweb/wp-content/uploads/2012/05/goslings.jpg : copy(oldweb.kbs.msu.edu/images/stories/Sanctuary/News_Item_Photos/goslings.jpg) [function.copy]: failed to open stream: No such file or directory

It’s interesting that the exact same problem occurs on a Unix system as on a Windows system.

I get a 403 Forbidden on https://oldweb.kbs.msu.edu/ when I try to connect with my browser.

Oops. Sorry about that. Fixed, I think.

I have tested a migration using https://oldweb.kbs.msu.edu.
I have created a sample article on my local Joomla database, whose content and image was the same as https://oldweb.kbs.msu.edu/education/k-12-partnership.
Results: it migrated the article and copied the image from https://oldweb.kbs.msu.edu/images/stories/education/gobles4.JPG to my local host without any problem.

So your problem may come from your target server.

I suppose it’s possible. But I went to the trouble of making sure the target uploads folder was world-writable, and that didn’t help.

I’ve since set up another pair of sites, of which the joomla site contains a bare-bones 1.5 installation with test data. I uploaded one photo and inserted it in the main examples page, then ran the import procedure.

The import procedure managed to copy the images (including my new one) to an appropriate folder in the uploads tree. But the import page reported that no media were copied. The new file is not seen in the media library. And the button for fixing links didn’t fix anything.

Did you write https://oldweb.kbs.msu.edu in the URL field ?
Are your media stored in year/month directories ?
Have you tried the import on your local host ?
Which plugin version and WordPress version are you using ?

I see I had written oldweb.kbs.msu.edu instead of https://oldweb.kbs.msu.edu. But now that I’ve got that right, I still get the same thing I saw on the minimal example.

1) All the images transfer. (Maybe this is progress!)
2) I get an error message for each transfer. But it’s not exactly the same error message. Now it’s “failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found”
3) When I do the update links step, nothing gets updated. The links in the articles still refer to the img in terms of the joomla folders.
4) The files are not listed in the media library. But yes, they are stored in year/month directories.

I’m using 1.4.1 of the plugin and 3.3.2 of WordPress.

I forgot to answer your other question about localhost. In all instances I’ve been doing a localhost import. I have not tried anything else.

I should also mention that I could open up the minimalist pair of sites and give you a password on it if you are interested in taking a look there.

“404 Not Found” means that this image is not found, in other words, there is a broken link in your post. You have this message for all broken image links.
Can you send me a copy of your Joomla database to kerfred at gmail dot com, so that I would be able to test it on my localhost and try to characterize your problem??

Yes, you can send them to me at the above email address.
