Can't install the plugin

Hi, loano1. Could you provide some more information about the issue you’re having? That will help us reproduce the issue.

– What version of the plugin are you using?
– What version of WordPress are you using?
– What version of PHP are you using (if known)?

Also, can you change WP_DEBUG to true on your wp_config.php file and share any warning/error shown after this?

Thanks again!

Hi Paulo,

thanks for your reply.

What I’m using are the following versions:

Plugin: 2.8
Wordpress: 4.4.2
PHP: 5.4.19

All I got is the message, the following file couldn’t be copied: fb-instant-articles/vendor/facebook/facebook-instant-articles-sdk-php/tests/Facebook/InstantArticles/Transformer/instant-article-example.html

Unfortunately wp_debug_log doesn’t show anything.

Regards,
Loano

Still having this issue that I can’t install this plugin although I’m now running the latest version of WordPress. Using a default theme and no plugins activated, I still got an error message:
Die Datei konnte nicht kopiert werden. fb-instant-articles/vendor/facebook/facebook-instant-articles-sdk-php/src/Facebook/InstantArticles/Transformer/Rules/FooterRelatedArticlesRule.php

Thanks for any help!

Hello again, @loano1. That is very bizarre indeed since the versions of your environment are the latest ones and even the PHP version is supported by the plugin.

Additional things I can think of to try:

– How are you installing the plugin? From the “Install New Plugin” screen within WordPress admin or manually by downloading the zip file? Try the 2nd option to do it manually.
– Does this same error occur when trying to install another plugin?

Other than that, an additional option to resort to is to wipe everything out and attempt a fresh installation of WordPress (only if you will be able to save/restore your content, of course).

Why is version 2.10 the latest showing for me? ??

@kademcconville, v2.10 is the current latest version of the plugin. If that’s not what you were referring to, can you provide more context to your comment?

Hi @paulo,

Thanks for your efforts. In the meantime I can tell you a bit more:

The error message I received was always on my xampp hosted local site. So I took the risk and installed it on our live site. I was able to install and activate the plugin and didn’t notice anything bad for a few days.

Then I figured out that when I try to update a page I get the following message: Warning: Cannot modify header information – headers already sent by (output started at …/wp-content/themes/Newspaper/includes/wp_booster/td_block.php:175)

The following code is placed on that position (Line 175):
echo $this->block_template()->get_css();

Finally I deactivated your plugin and our page works normal again. Maybe this helps you to improve your plugin further.
All the best!

Hi @loano1. You’re very welcome and thanks for the feedback regarding the behaviour in your environments and conflicts with other plugins/themes and potentially how to better improve the stability of the plugin.

I haven’t been able to reproduce a conflict like this and there haven’t been other related reports so I’m inclined to say this is an isolated case to your environment. As such, I’m marking this issue as resolved for the time being.

For posterity, if the Newspaper theme which appears to be generating the error is available publicly, could you paste the link to where it can be looked at?
