Preview error

Hi Stevem,

I’ve tested MailPoet with our debug on and with wp_debug on and I couldn’t see these Warnings you’re talking about. I’ve also tried on a automatic newsletter but couldn’t see the warning.

Can you please elaborate a little more what are you trying to do, this way you’ll help us find this issue.

Thanks for your feedback by the way ??

I have a weekly automatic newsletter which currently doesn’t have any posts in it, so it just contains the header and footer. If I go to
Mailpoet, Newsletters, then hover over the automatic newsletter and choose Preview (which is next to Edit, Duplicate, Delete) then a new tab opens with 21 lines repeating the error, followed by the correct preview of the newsletter.

Does that help?

It does, I just tried with the exact same setup and couldn’t see any Warnings.

Can you please get in touch with us here at https://support.mailpoet.com/ we’ll need to ask you private details about your website.

Please, don’t forget to refer this topic on the contact. Thanks!

OK, I have done that.

Hello guys, I’m seeing the same behaviour in my website. I’m seeing it in premium MailPoet but not in free versions.

Can you share the solution here if you find something? Please?
Thanks in advance.

Mailpoet support have solved this problem with a change to line 109 in render_engine.php. They say the error only occurs in PHP 5.4 and that the next update will correct it.

You can manually change it before then. This is their solution.
Change line 109 render_engine.php

from

if (isset($vars['border'])) $result[] = 'border: ' . $vars['border']['size'] . ' ' . $vars['border']['style'] . ' ' . $vars['border']['color'] . ';';

to

if (isset($vars['border']) && is_array($vars['border'])) $result[] = 'border: ' . $vars['border']['size'] . ' ' . $vars['border']['style'] . ' ' . $vars['border']['color'] . ';';

Thanks for the heads-up Steve. Did they told you about any ETA for the next update?

I’m afraid not. They said “We’ll publish a new version soon which will include this fix.”

Closing…
