4.4.1 apparently changed content in my posts and totally screwed up my mathjax

Please anyone?

Thanks for the reply! It’s not a plug-in. Just a simple JavaScript and not the cause of issue. The issue is when I updated enfold it removed backslashes in all my post content. When I restored backup version and dB everything was ok again. I’ll try to get a dev area up.

Hi,

Sorry I was traveling for a month but back. The script is really irrelevant. It just formats text equations from code, aka LaTeX. The code starts with a backslash. Upgrading enfold to newest stripped the backslashes from every post. Is that even conceivable on your end? Does your upgrade script alter post content? I’ll have the dev area setup later next week.

Take for example the first one. In browser source code view, looking at the post in WP or the database, you’ll see it starts with “\begin{align*}”. After upgrade it becomes “begin{align*}” and breaks.

Hi,

I kept it on 4.2.2 so you could see the before and then update to see the after :)

hmmm the script just goes in the header, it just renders the equation code. I looked in the database and the posts had the backslashes removed.

When you update wordpress it asks you to install gutenberg or classic editor.

Please update my test site. If you are convinced it’s not the theme, what else could it be? Should I deactivate all my plugins before updating?

With all plugins deactivated I upgraded and it happened again.

[tex]begin{align*} -c^{2} dtau^{2} = ds^{2}
= & -left( 1 – frac{2M r}{rho^2} right) c^{2} dt^{2} + frac{rho^2}{Delta} dr^{2} + rho^2, dtheta^{2} \
& + left( r^{2} + a^{2} + frac{2M r a^{2}}{ rho^2} sin^{2} theta right) sin^{2} theta dphi^{2}
– frac{4M ra sin^{2} theta }{rho^2} , c , dt , dphi end{align*}[/tex]

Should be:

[tex]\begin{align*} -c^{2} d\tau^{2} = ds^{2}
= & -\left( 1 – \frac{2M r}{\rho^2} \right) c^{2} dt^{2} + \frac{\rho^2}{\Delta} dr^{2} + \rho^2\, d\theta^{2} \\
& + \left( r^{2} + a^{2} + \frac{2M r a^{2}}{ \rho^2} \sin^{2} \theta \right) \sin^{2} \theta \ d\phi^{2}
– \frac{4M ra \sin^{2} \theta }{\rho^2} \, c \, dt \, d\phi \end{align*}[/tex]

Let me know if you want me to restore the backup for you to try and see.
