# PF5 Problems and Errors

Hi Greg:

I apologize if this "complaint" does not belong in this thread.

In the previous interface there was a feature that listed all the threads for which I had indicated my desire to "watch" it. That was very useful for finding older threads I wanted to read again. My current attempts to find and reread an old thread by using some search words I think might be helpful has rarely been helpful since at my age my memory is not so good. I hope some time soon that feature might be restored.

Regards,
Buzz

@Greg Bernhardt did you remove the new videos widget in the side panel in the home page?

Looking into it.

I faced the same in this thread:

#### Greg Bernhardt

There does seem to be some wrapping issues, but for the table example I'm not sure what could be done. How could that be wrapped? It should probably be converted to the new editor table. Even then it might not work. Not enough width.

You can fit the table within the space where the posts are normally visible, and enable horizontal scrolling.

#### Greg Bernhardt

I have specified line breaks to help force wrap equations, doesn't help tables. Let me know if that makes things better or worse.

I think that is something that would need to be added in the mathjax library.

I have discovered that I cannot edit the Summary section of the beginning post of a new thread.

Unintuitively the field is below the message editor.

Thank you much for your help. I apologize for not noticing things I should notice. It's an aging phenomenon.

I have discovered that I cannot use subscripts and/or superscripts or indents in either the Problem Staement or the Relevant Equations sections when trying to create an Advanced Physics Homework thread.

Can someone help me?

Hi fresh:

For most things what yopu showed me works fine. However, one of the equations I want to include has the following form.
f(xyz,) = x(yz)

I cannot make the x$^y$notation using "#" work for this. I would like to use the format bar that is usable for the text of the main section, but much of it does not work with the Relevant Equations or Problem Statement sections.

Regards,
Buzz

The format bar essentially just applies BBcode to format the text, so you should be able to insert BBcode. For example,
Code:
x[sup](y[sup]z[/sup])[/sup]
gives:
x(yz)

For more on BBcode see: https://www.physicsforums.com/help/bb-codes/

That is LaTeX, not the BB-codes [sub]/[sup]
They don't work in the problem description and relevant equations.

No changes visible from my phone, perhaps because of the screen size as you've mentioned. Haven't checked from pc, however.

A known issue. There is a link to the forum comment thread at the bottom of the insight.
