[Plugin: Yet Another Related Posts Plugin] Warning: strip_tags() error

How are you getting this from YARPP? That error seems to be coming from a core file.

I have the same issue:

Warning: strip_tags() expects parameter 1 to be string, array given in C:\xampp\htdocs\wordpress\wp-includes\formatting.php on line 631

Possibly interfering with another plugin?

lencanoot, are you using the builtin template or a custom template? Does the problem go away if you use one of the custom templates?

The problem also exists on other templates like Lightword. I add it to the index using the tag: <?php related_posts() ?>.

lencanoot, I’m confused… is this an issue with that theme or with YARPP? Or an interaction?

Doesn’t matter. All themes give the same error. So my own made theme does, but also the Lightword theme. Sorry I used the word template by mistake.

It gives me the formatting error as stated above.

Hey,
I am getting the same error …
Warning: strip_tags() expects parameter 1 to be string, array given in C:\xAmpp\xampp\htdocs\homerism\wp-includes\formatting.php on line 631
First I have deactivated and then activated all plugins … As u may guess it was useless … I dont have a solution but I have some clues and want to share them ;
– I am using Unicode template files encoded with UTF-8 BOM (Some local non-latin chars are used …)
– I have read an article about the compatibility issues with two-columns plugin. (If there are two columns … it comes custom wordpress queries or loops …)
– I am using custom wordpress queries(loop), custom wordpress template and also custom yarpp template …
This is it !
I hope someone can find a solution as soon as possible ; I dont want to look for another plugin, it has great features … (I hope it has …)

MaviDeve et al, where is this error being displayed? Could someone give me a link to a page which is doing this?

What I want to know is, if you’re calling YARPP using <?php related_posts() ?>, does it get displayed there or elsewhere?

Error is showing up in the div where you place <?php related_posts() ?> in the template file category-??.php or single.php or home.php … wherever u place <?php related_posts() ?>

Could one of you guys try commenting out includes.php line 396 or remove the strip_tags from keywords.php line 50? I think it’s possible that the first option would turn off the errors.

-or- by chance, are you all *not* using any YARPP template, with the display excerpt option on? In which case, does turning on a YARPP template, even the default one, help?

These three options cover all the ways in which YARPP ever calls strip_tags. I can’t reproduce this at all, so I’m trying to narrow down the possibilities.

Commenting out includes.php line 396 do not work out … nor keywords.php line 50 … Error is still there …

I’ve tried this out with a custom YARPP template and also with defaults, and without a template … but I am still getting this error … I’ve also activated and deactivated excerpt option ; but still no results …

I think I ll switch to WordPress Related Posts by denis for a while … ?? I know this is a great plugin but I ll be getting mad with that error … BTW thx for ur help, I ll be waiting for an update ?? If there is sth I can help u with to solve this issue, I ll be around … ??

@mavideve, the issue is frustrating indeed, but frustrating for me as well in that I can’t reproduce it for the life of me.

Those three points are the only places where strip_tags is used by YARPP. If you commented out all of those uses of it and you’re still getting the error, perhaps it isn’t a YARPP issue or it’s an incompatibility with something else. :/ Are you sure you turned off any caching as well?

Anyone else tried those?

Hey all,

Yesterday I moved my entire wordpress site from my localhost to my online server and the issue was gone..

Very strange. But other things changed as well: former IE/FF incompatibilities disappeared a I had to alter my IE stylesheet.

For the ones with the same problem, try migrating it to another server.

Still strange is that in some posts no related posts are shown while they do have used tags and are of the same category.

Btw, it’s online, so for an example go here:

https://www.getloud.nl/portfolio/?p=537#more-537

Underneath the post (it’s in Dutch) is the related post part. Left is the related posts, right is the posts from the same category.

I got the same error on MU 2.9.1 – it seemed to be coming from the_content(). Upgrading to 2.9.2 fixed it.
