can’t filter by category
-
Howdy! This is plugin is GREAT! A professor was looking for a way to export blog posts so she could create a book and she was thrilled with the output (HTML). Instead of the content of the ENTIRE blog that I’d pasted into a Word .doc, however, she was hoping to have content filtered by blog category and by author. Easy-peasy, I thought. Unfortunately, I can only export all posts. If I try to add a filter, or a user, or both, the page just hangs on “Loading Content”. I can’t figure out what’s wrong. I’ve tried clearing my cache and using the latest version of Firefox and Chrome, but I just can’t filter. Any ideas?
https://test-of-pursuitofhappiness.academic.wlu.edu/ is a duplicate of the actual site, which is https://pursuitofhappiness.academic.wlu.edu/ – but the live site has a private plugin so it’s only accessible to logged in users.
I tried using https://printmy.blog/ and can filter https://test-of-pursuitofhappiness.academic.wlu.edu/ by category, but not by user. All users are authors, not sure if that matters. I wasn’t able to get it to “see” the different categories of pursuitofhappiness.academic.wlu.edu, even after deactivating the PrivateWP plugin.
Thanks for reading and for any help you can provide.

Hi @hmacdermott, thanks for the encouragement! But sorry its giving you grief…
If I try to add a filter, or a user, or both, the page just hangs on “Loading Content”
Can you send me the URL of the page where you see it stuck on “Loading Content”? Because the URLs I’ve tried for https://test-of-pursuitofhappiness.academic.wlu.edu/ worked ok. Eg I could filter by category ok, here’s the link to it. Do you still get the problem on that page?
I did see printmy.blog can’t load the test site’s authors. It looks like you have a security plugin active that’s preventing it from listing authors. Which security plugin do you have active on that site?
I wasn’t able to get it to “see” the different categories of pursuitofhappiness.academic.wlu.edu, even after deactivating the PrivateWP plugin.
Do you mean the printout didn’t say which categories were included in the printout? (ie, on printmy.blog’s print setup page the dropdown list of categories worked ok, and you selected one, but when went to the print page, it didn’t say what categories you had chosen earlier, even though only posts with the selected categories appeared.) If so, I’m sorry that was deficiency of printmy.blog; but the self-hosted version of the plugin does say what categories were used in the printout… But if that’s the issue, I can see what I can do to improve that.
No, I don’t know how to enable the WP REST API.
The WP REST API is enabled by default, but often security plugins disable it, especially listing site users. So you don’t need to find a *new* plugin to enable it, you need to find out which *existing* plugin, that’s already activated on your site, has disabled it.
But I downloaded and enabled a plugin — WP REST API Controller — and enabled user_request (“Expose the User Request post type to the REST API.”) for both sites. Would that do the trick?
That *sounds* good, but I think there was already a plugin that had deactivated listing users over the REST API. So I don’t think adding another plugin on top of it would fix it. You need to find which existing plugin had disabled it, and turn it off (or find the setting that disables is.) I’m pretty certain it would be a security plugin (eg [there’s a related FAQ](https://www.ads-software.com/plugins/print-my-blog/#the%20print%20page%20says%20%E2%80%9Cthere%20seems%20to%20be%20an%20error%20initializing%E2%80%A6%E2%80%9D%2C%20or%20is%20stuck%20on%20%E2%80%9Cloading%20content%E2%80%9D%2C%20or%20i%20can%E2%80%99t%20filter%20by%20categories%20or%20terms%20from%20the%20print%20setup%20page).)
You’ll be able to see when it’s fixed by visiting [this WP REST API page that lists users](https://test-of-pursuitofhappiness.academic.wlu.edu/wp-json/wp/v2/users) (which returns a bunch of machine-readable text called “JSON”, although it’s kinda readable by us human as well) and instead of seeing the phrase “Sorry, you are not allowed to list users” in that mess of text, you’ll see a mess of usernames and stuff.If you don’t have any security plugins active on the site that’s doing that, it’s possible your network has a security “Must-use plugin” installed (which you can’t deactivate, and is basically hidden).
And regarding the URL that just hangs on “Loading Content”: it seems to again be a security plugin that’s doing that. Normally, Print My Blog loads posts in the background using the WP REST API, but on your site(s), when it requests posts by a specific user, it gets back an error page (HTTP 404) instead of a valid JSON response.
So, for both issues: there’s either a security plugin or some network-wide security setting that’s disabled parts of the WP REST API that deal with users, which Print My Blog needs to work.
If you have a sys admin you can talk to, I’d suggest asking them what security plugins, must-use plugins, or even webserver security settings are active. If you’re the sys admin, you could tell me what security plugin(s) you have on your site, and I can try to figure out which one is causing issues.
