@Anthere I tried to reproduce this bug but it seems on live there is no campaign with id 288. Please could you give more details, such as the campaign name?

There is one... this is "Wiki Loves Africa 2022 Home + Habitat » campaign.
Started 2022-11-01 and closed 2023-01-15
(it is a closed campaign now)

This is a large campaign (15912 images and 95413 contributions)

And yes... it is not loading anymore at all on my side

It's 288, not 228. Just click on the given link https://isa.toolforge.org/campaigns/228/stats and you'll be able to replicate it too.

I can replicate the bug.

I can also reproduce this. I tried locally too and while it didn't result in an error it took 40 seconds to get the response. A very quick debug shows that in getCampaignStatsById() the call of get_all_camapaign_stats_data() took 10 seconds and get_table_stats() 40 seconds. Then rendering in the browser took about 30 seconds.

I finally figured out a possible technical issue with that route. Submitting a fix for this.
