Hello everyone,

I have a website with 6GB of cached k2 images. I need to transfer the website to another server and i want to delete k2 image cache, upload it and rebuild the cache on the new server.

Is that possible?

Thanks!

Thank you for the reply,

Can i also exclude the sizes that i do not use (e.g small)?

Yes, in the direction is says: Check Variables, use a size of 0 for not processing this image size

thank you!

Hi I've tried this but only works for the first 70 images... any idea why am i doing wrong.. or how can make it work for all the images. I have 600 images in total.

Are you sure you are not experiencing PHP Memory limit issues?

Hello,
I have the exact same problem but I don't understand 2nd and 3rd line.

2) Check Variables, use a size of 0 for not processing this image size
3) run it "php -f rebuild.php" (it overwrites existing files without notice)

What does this means? Run it from where?

I tried running it from the url as a path and it gets me to the github url.

Thanks,
S@

Can I run this tool in the remote web server, or only if I have SSH access to it in order to use the php command line?

ok so - have figured this out being also a non developer. The file they have you downloaded is a html sort of file actually and not a real php file - below is the php part - copy this and paste in new file and save as rebuild.php - then to run it, just open it on your web server by just adding /media/k2/items/rebuild.php after your url like localhost/testsite/media/k2/items/rebuild.php

This will then actually run the script - as they said, it takes a long time to run so make sure your max_execution_time = 6000 in your php.ini file is set high - i changed mine to 6000 for the test.

hope this helps someone like me that did not understand run it :woohoo:

oh - remember to change the sizes in the first part of the script to replicate your parameters and the quality setting - that is all you need to change.
