problem

When do you get this error?

When I search for a category name

Does it always happen when you search for a category name, or only with some words? The more detail you can supply, the better.

Only category search

Can I see this in action on your site? With this much information, I don’t really know where to start trying to reproduce the error.

Hi I have the same problem when I search for a term.
The error message:
Warning: mb_stripos() [function.mb-stripos]: Offset not contained in string in /home/ecosupp/domains/ecosupp.co.il/public_html/wp-content/plugins/relevanssi/lib/common.php on line 677

relevanssi version 3.5.5
wordpress: 3.7.1
domain: https://www.ecosupp.co.il

It happens in all search

Samisraeli, do you have Relevanssi enabled at the moment? I don’t see the error. Can you tell me a search term that causes the error to appear?

Anyway, could you please try this for a fix. In lib/common.php in the plugin folder, find this line:

function relevanssi_stripos($content, $term, $offset) {

After it, add the line:

if ($offset > mb_strlen($content)) return false;

Does that make the problem go away?

The reason you didn’t see the warning was that I disabled the display of warnings in the wp-config file.
After I added the line, it seems ok now.

Thank you for your prompt reply.

Thank you,

Sam
