Warning after activation: The plugin generated 241..

?? Same error message here… seems like the new upgrade needs a fix ASAP.

Same Error Message…
The plugin generated 257 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

Great plugin – but unfortunately same here too:

The plugin generated 235 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

Also see PHP Warnings about rtrim on various CPT archive pages:
Warning: rtrim() expects parameter 1 to be string, object given in /home/user/html/wp-includes/formatting.php on line 1381

Same issues occurring for me in 1.4.2 and 1.4.3

WordPress version: 3.5.1
WordPress SEO version: 1.4.3

The plugin generated 287 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

I performed a downgrade to version 1.4.2 and the same problem persists. The 1.3.4.4 version installs without this error, but the error with the XML sitemap happen again.

WordPress version 3.5.1
WordPress SEO version 1.4.3

The plugin generated 243 characters of unexpected output during activation...

Errors occur with custom child theme (based on Hybrid parent theme) as well as default Twenty Twelve theme with no other plugins active.

Tried development version with same results. Downgrading to version 1.3.4.4 eliminates the errors. Not sure is downgrading will result in XML sitemap issues.

Doesn’t look like this is going to get resolved!

What is everyone doing regarding this issue? Can anyone recommend any alternatives?

I installed 1.4.1 this gets resolved.

Hey ls41,
Actually version 1.4.1 does not show the error in the installation.
But the error sitemap, which prevents the generation of the same, so that it is not generated.

XML Parsing Error: no element found
Location: https://www.xxxx.xx.xx/sitemap_index.xml
Line Number 1, Column 1:

Test performed with version 1.4.1 SEO and 3.5.1 WP.

Just pushed out 1.4.4 which fixes this error.

Thanks..!! ??

?? Thanks Joost

Either this is simply serendipitous coincidence,
or I guess twitter IS good for something.

??

nice one Joost – all good now.
Thanks for all your work ??

Big TY

Just pushed out 1.4.4 which fixes this error.

I know this thread is 9 months old, but where can I get hold of 1.4.4?

On your site I can only download 1.4.21 – and what exactly was it you did that fixed it?

Remove white spacing from your code that might help.
