PHP Err: undefined offset in Minify.php

Hi pietari-pate

What is your php version?

And would you please go to /home/xxx/public/xxx/wp/wp-content/plugins/w3-total-cache/lib/W3/Plugin/Minify.php on line 165 and replace
&$this
with
$this

Let us know if you get the notice then too.

Have an awesome day!

Cheers

You need to check line no 165. What do you see in there?

Ahh yes, my bad, I am sorry, I was looking at wrong file.

Would you please replace

$embed_pos = strlen($match[0][0]) + $match[0][1];

with the following?

$embed_pos = isset( $match[0][0] ) && isset( $match[0][1] ) ? strlen($match[0][0]) + $match[0][1] : 0;

Hope it helps 🙂 Please feel free to ask more question if you have any.

Cheers
Ash
