ehku Posted March 10, 2015 Share Posted March 10, 2015 After upgrading from 3.4.7, I realised that the string "<wbr></wbr>" has been randomly added to topic titles. This is a critical issue for me since my forum is a math forum and the added string caused the formula not displayed correctly. I use a Javascript display engine called MathJax, to turn TeX code to formula. For MathJax to recognise a formula, it must be put between two symbols $, i.e. ${formula code}$, as that there's no line-break other than <br/> (MathJax does allow this line-break, see more: https://groups.google.com/d/msg/mathjax-users/-7PcQ1sxZ6c/dEYm5u_WEQ8J). Example: $\frac{a}{b}$ will be displayed as . As you can see from the above photo, the string "<wbr></wbr>" was added to topic titles, which caused the formula not being displayed (the formula is displayed well in the blue box). I would appreciate it if somebody can suggest a solution. @Mark Thank you. Link to comment Share on other sites More sharing options...
3DKiwi Posted March 10, 2015 Share Posted March 10, 2015 I would revert your site back to 3.4.7 from a backup as soon as you can. Get yourself up and running properly with what you had before.Now wait until the release version of IPB 4 is out. Set up a copy of your 3.4.7 forum and do a test upgrade. If the problem persists file a support ticket. I reckon you'll be praying for a miracle to try to fix things with what you've ended up with.

I had not been thinking of upgrading my live site until IPS 4 is really stable (maybe in a few months) until I made a serious and stupid mistake, unfortunately. I created a duplicate of the site and the database, applied all the necessary changes via FileZilla, and then upgraded the duplicate to 4.0RC4. The problem is, I forgot to change the permissions of the config file (default is non-writable), and FileZilla didn't warn me about that (there's a tab called "failed transfer" but honestly I don't have the habit of looking at that every time I save a file). Therefore, the paths and the database in the config file are those of the live site, and as a result, the upgrade ended up with errors, and the live database was converted to 4.0 (maybe not properly) without having a working site associated to it. Unfortunately the last backup of the database was 2 weeks old, so I decided to continue to fight with 4.0.But now, your comment makes me re-think of reverting back to 3.4.7, even though I will lose some data, that might be better.Thanks again.

A <wbr> tag is invisible and 4.0 adds them to topic titles deliberately when displaying. The issue ehku is experiencing is just that his custom JS doesn't work with 4.0 anymore because of that.I'll have a think about this tomorrow.

Mark Posted March 12, 2015 Share Posted March 12, 2015 I haven't forgotten about this. I think I've convinced them to change MathJax itself. Link to comment Share on other sites More sharing options...

ehku Posted October 23, 2015 Author Share Posted October 23, 2015 Hello @Mark. The above problem has been resolved, but now I'm having another annoying problem (always related to MathJax). One often encounters repeating or similar terms/expressions in math formulas and it's a pain to (re-)typing everything instead of just copy-pasting. However, when doing copy-paste of a text in the editor, it results in something like this: <span style="line-height:22.4px;"> copied text </span> This is not good at all since it adds html code to the formula, resulting in invalid ones (the same problem as the above, with the <wbr> tags). Is there a way to prevent the editor from adding those code? Thank you in advance for your support. Link to comment Share on other sites More sharing options...
Jim M Posted October 23, 2015 Share Posted October 23, 2015 Are you pasting in the editor in plain text? Link to comment Share on other sites More sharing options...

Ctrl+C and Ctrl+V, so, no The editor should know that I didn't apply any formatting to the text (to be copied), and thus it should not apply any formatting either to the copied text, shouldn't it?

The editor sees that the text you copied has formatting thus replicates it In 4.0, you can setup your setting in the editor so everything pastes in plain text by clicking the settings cog wheel (if you have the default tool bar). Alternatively on Windows you can do CTRL+SHIFT+V to paste in plain text. Link to comment Share on other sites More sharing options...

ehku Posted October 23, 2015 Author Share Posted October 23, 2015 @Mark @Jim M: I have another problem. When right-clicking on MathJax formulas, the contextual menu is hidden behind the main area layout Link to comment Share on other sites More sharing options...
Jim M Posted October 23, 2015 Share Posted October 23, 2015 Sorry, I am not familiar with this JS extension, does it come with a CSS file? Link to comment Share on other sites More sharing options...
Martin A. Posted October 25, 2015 Share Posted October 25, 2015 It's because the z-index for the contextual menu is lower than the <main> area, which is set to 1000. The menu's index is 200. In the JS you have this line: BGSTYLE:{position:"absolute",left:0,top:0,"z-index":200,width:"100%",height:"100%",border:0,padding:0,margin:0} Change that to BGSTYLE:{position:"absolute",left:0,top:0,"z-index":2000,width:"100%",height:"100%",border:0,padding:0,margin:0} Link to comment Share on other sites More sharing options...
