These are awesome, nice job!

Upgraded from v1.45 to v1.49.

Now, when launching my application, the sidebar temporarily displays–exposing all of my .py files in the pages/ directory before permanently disappearing (not collapsed) and my sidebar is not accessible.

Finally, my page_config was (partially) st.set_page_config(initial_sidebar='collapsed'

Can someone please explain what happened and how to fix? Thanks.

EDIT / UPDATE: ———–

Currently, I am setting the page config in a utility file (for all my page configurations to be nicely packaged in one location (e.g. import … as VFR, VFR.set_page_config()).

This is apparently the problem, as when I create a test file and embed the st.set_page_config() within the test file, a sidebar displays as expected.

I assume it has something to do with v1.46. Not really sure why the st.set_page_config() needs to be called multiple times in a page and all users have worked around this limitation thus far. Comment and pull requests like this ( set_page_config() issue in Microsoft edge · Issue #9797 · streamlit/streamlit · GitHub ) don’t even seem to be good practice!

So, can I get a Steamlit developer to confirm that instead of calling a single wrapped function for all of my page configurations, the best practice is now to copy/paste the same 16 line function across all 18 of my app’s pages?

It seems like the major user reason is to change the Page Title instead of creating a new page that requires a little more development work in the era of AI? I can only imagine how much debugging was required to implement this breaking change (for what appears to enable poor app structure and technical debt on the end-developer’s codebase).

@mathcatsand

st.set_page_config can be called multiple times in a single script run (#11286, #4483, #2216, #9797, #9038).

[Darshankumar]

st.pdf not working…tested on sagemaker with all permissions already signed to pdf.

[lperezmo]

did you try installing the required dependencies withpip install streamlit[pdf]? st pdf docs

[Darshankumar]

Yes, I tried. even after that it was showing some security level message, even when the pdf was public whether it was from GitHub, conference or from local.

Since i had a deadline, i went with hyperlink

[mathcatsand]

@ryanlampkin The change to st.set_page_configmakes it more compatible with the newer version of multipage apps where you call it once in your entrypoint file to set a general default, and then call it again on the specific pages where you want to deviate from that default. I think that was a bigger reason for removing the restriction, although, yes, it also allows you to now call it repeatedly on a single page to change the title or icon over and over if you want.

Can you create a new thread or GitHub bug report with some minimal, executable code to demonstrate the issue you are having with the configuration?

[edward.ball]

I also cannot get st.pdf to work - I get this error whether I try a local or public network pdf.

[mathcatsand]

@edward.ball Streamlit and streamlit-pdf both got patches. Can you confirm if the error persists after upgrading both. Then if it still occurs, please can you file a bug report: Sign in to GitHub · GitHub

[ryanlampkin]

The problem was not with st.set_page_config().

The problem was within a different aspect of my helper function when setting CSS styling for the former “header” class – possibly this: Theming: Remove colored decoration line by mayagbarnes · Pull Request #12155 · streamlit/streamlit · GitHub

In any case, I removed my custom CSS related to this. I temporarily also removed:

    footer {{
        visibility: hidden;
    }}

and it seemed to have no effect. Perhaps Streamlit removed the auto-generated footer at some point too; however, I’m not sure why the header version of that CSS styling caused problems and the footer styling did not (maybe bottom of page stuff).

I also had problems with the sidebar when I upgraded from v1.45 to v1.49.
If I disable the default Streamlit header (Deploy button and Menu) in CSS, the sidebar is also disabled.

My solution was to make the header transparent instead of disabling it

header.stAppHeader { 
    background-color: transparent;
} 

Does anyone have another solution?
