Hi @kramarz,
Can you enable debug log on your site and check debug.log, what error you are getting?

Funny, it stared to smush now, but then stopped after some images…
Anyway, this is the debug note:
[16-Apr-2015 11:19:49] PHP Fatal error: Allowed memory size of 52428800 bytes exhausted (tried to allocate 219053 bytes) in …/httpdocs/wp-content/plugins/wp-smushit/wp-smush.php on line 549
Further investigating it looks like it just throws that error on images around 200KB or bigger, smaller sized images get processed no problem when doing so manually.
Ok, solved the problem by adding
define(‘WP_MEMORY_LIMIT’, ’64M’);
in wp-config.php
Don’t know why that helped cause website is kind of light as to using resources, but… smushing works fine now.
So marking as resolved, but if you would have anything to add, please do 😉
Hi @kramarz,
That makes sense, too low memory was allocated, 52MB.
Smushing includes file operations, reading and writing, it requires more memory.
It’s good, if it works at 64M for you, otherwise keep it at 128M instead.
Cheers
