All websites returns blank page

When i click to show all websites i get a blank page. I have even tried to reset the tmp folder like i read but it still does not work. i can go to individual stats but not all and with over 900 sites its a pain to try and do each seperatly

This is a known bug: "All Websites dashboard" should load fast even when tracking hundreds of websites! MultiSites · Issue #1077 · matomo-org/matomo · GitHub

there is some work in progress by capedfuzz to make it faster, but definitely slow when hundreds of websites (you can use the API with idSite=all) and it will be faster if you need the visits count for all sites.

Hello,

I’ve encountered the same situation, but its unrelated to speed, but to a Smarty related issue. I opened a ticket at: All websites html rendering fails with many websites · Issue #3715 · matomo-org/matomo · GitHub
