[Resolved] error after update to 1.3.23: strpos(): empty needle in /media.php on line 1088

[Sven]

Hi Tom,

yesterday I updated my GP-theme as you published a new version. Since then I encounter an error on my front page (where I use sections):

“Warning: strpos(): Empty needle in /homepages/sven-koeck.de/wp-includes/media.php on line 1088”

There appear 6 lines of identical content.

I deactivated all plugins and GP Premium and GP-add ons. My start page uses sections so I only activated GP Premium with add-ons (sections only) and tada: the error appears!

Could you please take a look at your theme files (especially media.php)? I appreciate your answer!

Best regards,
Sven

Hi there,

media.php is actually a WordPress file, and 1.3.23 has been out since December 21.

What version of GP Premium are you using?

Can you try #1 on this page to see if it’s another plugin causing the issue?: https://generatepress.com/knowledgebase/debugging/

[Sven]

GP Premium 1.2.74

[Sven]

I have deactivated ALL plugins and only activated GP PREMIUM and SECTIONS –> error!

WP: 4.4.1

[Tom]

Can you try updating to the latest version of GP Premium (1.2.79)?

[Sven]

GP premium updated to 1.2.79 –> error persists

(please also notice my personal mail to you concerning activating email)

Hi Tom,

I installed Theme Twenty Sixteen and changed into live-preview. There were some error messages:

Perhaps they’re the problem and you can interpret an correct them?

Solved it!!!

I’m using the Lighweight Grid Column plug-in. I had eight images with class-attributes ==> 8 error lines.

First I suspected the LGC-plug-in, but it were the class-attributes to the corresponding images… deleted one ==> 7 error lines.

Deleted all class-attributes… and the error is gone! 🙂

Do you have an explanation for that beahaviour? Or at least a suspicion?

That is very strange – typically, HTML errors shouldn’t create PHP warnings/errors.

Either way, I’m glad it’s fixed now 🙂

For me this error is still present:

“Warning: strpos() [function.strpos]: Empty needle in /home/depende/public_html/wp-includes/media.php on line 1088”

If I return to this line in 1088 ($src_matched &&) in media.php from “false” to “true” the error error disappears…

// If the file name is part of thesrc`, we’ve confirmed a match.
if ( ! $src_matched && true !== strpos( $image_src, $dirname . $image[‘file’] ) ) {
$src_matched = true;
}

Any suggestions?

Hi Marco,

on my blog page (as well as in the posts itselves) that error message appears above the featured image any time I use too small images…

I have set the basic width of any featured image in my posts to 1200×800, so the error appears after using images which are smaller. As soon as I use larger images, the error disappears!

Hope that can probably help you!?

Hi Sven, because on pages 4 and 5 of your site I see this error again?
See: http://sven-koeck.de/blog/page/4

It seems some others are having this issue as well: https://wordpress.org/support/topic/warning-strpos-empty-needle-above-images

I’m wondering if it’s a WordPress 4.4 issue? I haven’t experienced it yet on any of my sites. Maybe it’s server related?

[Marco]

I think so, it started with 4.4.1… any workaround for now?
