How to increase the WordPress Multisite Network limit for Maximum Filesize Upload or Upload Limit Exceeded? Print

If you have run into an error when trying to upload images to a site within a WordPress multisite network, there a couple of settings that you can check to see adjust the limits.

Max upload file size

If you receive the error "FILENAME exceeds the maximum upload size for this site." this indicated that the individual file has exceeded the limit set in WordPress Network Dashboard => My Sites => Network Admin => Settings 

Navigate to this admin options page and look for the setting Max upload file size (by default set to 1500 KB)

Upload Limit Exceeded

If you receive the error "Sorry, you have used your space allocation of (x)MB. Please delete some files to upload more files." then your individual sub-site has reached the maximum combined limit of files allow to be uploaded.

As a network admin, to fix this navigate to the same settings page WordPress Network Dashboard => My Sites => Network Admin => Settings and look for the Site upload space limit.

Be aware that these settings will affect all websites in the network.

Encode and I had a very useful discussion about Wordpress and related issues at no cost to myself. He gave me some very helpful information and answered the questions I had.

I learnt quite a lot! Thank you.

I am very excited to work again with Neil. His attention to detail is second to none. I have seen his work in action in the past and he is great. I love his calm approach and his patient guidance to non-tech people like me. I would highly highly reccommend him!

Neil is the best! He has sorted out all our business emails and everything runs a great deal better now. Website issues are now a thing of the past as Neil has introduced a maintenance programme to ensure the site is always working optimally and any content changes are actioned pretty much immediately.

Highly recommended!!

'Encode' provided my hosting and domain transfers. They were able to deal with the technicalities of the transfer in a particularly speedy manner, taking all the worry of the transfer, domain issues DNS and nameserver headaches as well as the migration. A couple of emails, and phone call meant it was done smoothly, swiftly and efficiently. All I can say is I'm really please they were recommended to me. Thank you
