PF5 Problems & Errors: Report & Discuss

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

Can anyone help me?

Can anyone help me?

Unintuitively the field is below the message editor.

 

[Buzz Bloom]

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

 

[Buzz Bloom]

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?

Worked for me. I typed in "Test of # # SUB_n # # and # # SUP^m # # elements. (without the blanks)

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,

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.

Let me know if that makes things better or worse.

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

The page for the insight "Understanding Superposition" says I must be logged-in to comment, but I am logged-in. When I click on the "logged-in" link, I don't get any option to log-in.

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

What happened to the two rows of symbols, ie. Greek alphabet, math that were available with replies?

What happened to the two rows of symbols, ie. Greek alphabet, math that were available with replies?

It's on the $\sqrt{x}$ sign.

 

[morrobay]

It's on the $\sqrt{x}$ sign.

Well I don't see that sqrt(x) sign in this reply page, where is it, thanks

Maybe a limitation on this phone but the row I have ends at the counter clockwise arrow and the row does not slide to left to sqrtx.

But I do have that on my phone. If all icons cannot fit into one line, they will make a new line:

The operating system of the phone might be helpful to know.

It's a lava 550 cheap phone, android I believe. Maybe the upgrade got ahead of this phone. I have to go to internet outlets for uploading...

 

[Ygggdrasil]

I also do not see a link for the symbols when accessing the post editor on my phone (Android 9, Chrome 75.0.3770.89)

It is, however, understandable that the mobile post editor would not have all of the same features of the editor available on the desktop site.

 

[morrobay]

That is exactly what my reply screen has. How about exchanging the order IE put sqrt(x) in place of smiley faces.

 

[mfb]

With iOS
You can type ## at the beginning and end manually, an icon for it doesn’t do much.

 

[Wrichik Basu]

@Ygggdrasil and @morrobay Have you tried using Desktop site (that is, enabling Request Desktop Site in Chrome)? This might solve the problem. I always use the desktop site even when working from phone.

 

[morrobay]

Not that internet savvy for running around. Again why not put the sqrt(x) in place of the trite smiley faces ?

Here's a couple of related bug that have been annoying me a little.

I start from this page to see unread messages - https://www.physicsforums.com/watched/threads?unread=0. If I then click the Forums tab and select Mark Forums Read, it sends me to the PF home page for some reason. Then, when I return back, the previously unread messages are still highlighted until refresh the page.

I have also seen lots of cases where threads stay highlighted after clicking on them using their link in the Alerts dropdown. I know that you have to visit the last page in the thread for them to get marked. Still, there are many times where I will return to my starting point and have to manually refresh the page in order to see which ones I haven't read yet.

If you press the back button on your browser, it will actually take you to the previous page and display it in the form that you saw before you left it. This is true for almost all web sites which don't refresh the page automatically.

As you are marking all threads read, you are being taken to the PF homepage. If you go back to the previous page by again clicking on the link (that you pasted above), you will see that all threads are marked read. If you, however, go back from the browser, you have to refresh the page to load the changes.

Similarly, say you post a message in a thread, and go to some other thread. If you return to that thread by pressing the back button from the browser, you will not find your post until you refresh the page. This is something that I always face.

 

[mfb]

While it is possible to change websites "live" (as it is done for the alerts as gold feature, for example) this is only used in important places. Normally the website stays as it is until you reload it, and that's the way it should be.

 

[Borg]

I only noted it because PF didn't behave like this before. Previously, hitting the back button on the browser didn't require any additional steps to un-highlight the thread that I went to.

In viewing https://www.physicsforums.com/threa...ferential-chapman-kolmogorov-equation.972377/ in Firefox, I see the edit window can overflow it's right margin and be obscured by the forum self-advertising.

LaTeX issue. Already discussed here:
