Yesterday I did my first installation ever of XOOPS on a site I am developing.
Everything went fine until today, while I was adding and previewing a Custom PHP block, the browser froze and crashed. When I came back to the site, I was surprised in only seeing a blank page.
I tried everything to fix this but with no success, then I almost accidentally tried to enter in something different than the home page, and it worked. I was able to log in and see everything, even the home page, I checked that nothing was out of order... but still, if I logout and try to see the home page I only get a blank page instead.

In summary, I can only see the home if I'm logged in, otherwise it is blank.
The debug mode shows nothing, just a few warnings which I also corrected but without any improvement. I changed the theme, reloaded it, tried to make changes to see if anything happened: nothing changed.
Can anyone help me with this? Thank you.

kccmt, Welcome to the XOOPS forum!

What code did you add to the custom PHP block?
Are there any messages when debug is on (preferences system general)?

Thank you :)
I didn't add anything to the block I was just previewing it and it never was actually added (it was a simple code to embed a flash clock, anyway, and worked properly in its own page).
The debug mode showed me a few warnings (corrected), a couple of notices and the usual list of queries and such, no messages.

Uhm... problem solved, it seems. Now it works. I swear I didn't do anything though.
