What version of the plugin are you using?
This should have been fixed in v1.1 via https://github.com/ampproject/amp-wp/pull/1987/files
We are on version 1.1.1
I see that line in our current plugin, so it seems odd that we are getting the error.
We are on PHP 7.2.17 but it seems to be acting like INTL_IDNA_VARIANT_UTS46 isn’t defined. I’ll do some digging on our end.
@westonruter the issue seems to be with the PHP installation on our server. We are working on a fix.
Thanks for the quick response!
This typically happens when the version of PHP has been compiled with an older version of ICU.
@swissspidy thanks for that insight.
Hi,
I start getting the same error when open a post to edit, class-amp-http.php but on line 233. Looks like it starts after the latest plugin update. I have php 7.3
@edwardsh Might be the same issue – new PHP version compiled with an old version of ICU. I suggest contacting your hosting provider to get this fixed.
Pascal,
thanks for your reply. How can I check out the ICU version? Is this possible via WP or Plesk console ? I have no ways to ask my hosting provider.
@edwardsh You would need to somehow display information about your PHP version using “PHP Info” (<?php phpinfo(); ?> or php -i on the command line). Unfortunately I don’t know how this is doable in Plesk console.
The relevant part should look like this:
intl
Internationalization support => enabled
ICU version => 63.1
ICU Data version => 63.1
ICU TZData version => 2018e
ICU Unicode version => 11.0
Directive => Local Value => Master Value
intl.default_locale => no value => no value
intl.error_level => 0 => 0
intl.use_exceptions => 0 => 0
The relevant part is the ICU version there.
If the version is too old, it would look like this: https://user-images.githubusercontent.com/841956/54491179-9b6a5780-48bc-11e9-8a06-420962738dd0.png
