Issue importing a large site, can not define the issue myself.

[dewwwald]

I think the issue might have to do with images being loaded before a page is save, however this is just a guess based on function names. Here is some more information

Reason for suspission

In the linked topic soma talks about saving a page before you can load images as the files where the images will be saved to wont exist.

Running the importer a second time by reloading the error page successfully loads the page with no errors.

Thanks for the detailed report. I don't think I have ever seen an issue in Migrator where images have caused an issue with pages not created yet. It is supposed to deal with all that. Although it is interesting that it worked when you imported again - are all the pages and all the content now imported?

Am I correct in assuming you are importing a Wordpress site, rather than content from another PW site?

Any chance you could PM me the file you are trying to import so I can test?

Hi. @adrianbj. Thanks for the swift reply.

Sorry I havent gotten back to you yet. I was away from my computer and internet for the weekend. I am using the wordpress plugin by nico to import a wordpress site. Might this be an issue on the plugin instead of the migrator?

About the file, I am sorry, I don't think I can do that. I might be able to recreate the data. Or at least the issue with Lorem data and Lorem images.

This will take me a while. Give me a day or 2.

[adrianbj]

Before you go to any trouble recreating data, can you please try upping your php memory limit and maybe even the max_execution_time - this is actually set at the top of the migrator file as well. I know that Joss had some similar issues to you, but on my setup it worked fine.

Also, what version of PW are you running? That "Trying to get property of non-object" error might be related to this: ryancramerdesign/ProcessWire#813 which Ryan fixed in PW dev.
