@ihsaan-ullah Is this solve even if there are several pages of competitions?

It solves the buttons showing for a second before competitions are loaded.
I am going to check the behaviour when we have several pages of competitions

But I think the pagination does not work on https://www.codabench.org/competitions/public/

[Didayolo]

In the past the pagination was working... Maybe there is just not enough competitions to have multiple pages

[ihsaan-ullah]

Then it should be working. Not sure what is the limit in the page

codabench/src/static/riot/competitions/public-list.tag

Line 3 in 3dde7ea

<div class="pagination-nav" hide="{(get_array_length(competitions.results) === competitions.count) || (get_array_length(competitions.results) < 10)}">

I am not sure about the second condition if it is working

(get_array_length(competitions.results) < 10)
