Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Hi @wlabarron,
Do you know if you have the
php-tidyPHP extension installed?That would be my first guess if this occurs on any page in your instance.
@wlabarron commented on GitHub (Mar 25, 2020):
Hey Dan,
php-tidyisn't listed when I runphpinfo();inside mypublicdirectory. Should it be?@ssddanbrown commented on GitHub (Mar 25, 2020):
@wlabarron Ideally there should be some mention of
Tidyin there. What operating system are you running BookStack on and what method did you use to install it?@wlabarron commented on GitHub (Mar 26, 2020):
I followed the Manual Installation Instructions, and it turns out I do have
tidyinstalled (I searched the page forphp-tidyoriginally, hence no results). I'm on shared hosting, I know that it's not officially supported, but I was able to run all the install commands without issue so I ran with it. Looks like my server is running Red Hat, or at least that's what's listed in/proc/version.@ssddanbrown commented on GitHub (Mar 27, 2020):
@wlabarron Okay, Thanks for confirming.
This page details how you can enable debug mode in BookStack:
https://www.bookstackapp.com/docs/admin/debugging/
Could you follow that to gain more information and hopefully we'll get a handy error message when you click changes with debugging enabled.
@wlabarron commented on GitHub (Mar 27, 2020):
@ssddanbrown Yep, got an exception (on a very lovely error page):
Required Tidy extension not found.Odd, since it is listed inphpinfo(). Runningcomposer show, however, doesn't listtidy.@ssddanbrown commented on GitHub (Mar 28, 2020):
@wlabarron Hmm, Might be worth checking your
php.inifile to see if the tidy extension is commented out in there.@wlabarron commented on GitHub (Mar 28, 2020):
@ssddanbrown There's no
.iniinside my BookStack installation folder. There is one in my home directory which it's probably inheriting info from, but that has no mention of the Tidy extension. Should there be one in my installation folder?@wlabarron commented on GitHub (May 19, 2020):
This issue has resolved itself - seems like one of the last couple of updates has fixed whatever was set wrong.
@ssddanbrown commented on GitHub (May 23, 2020):
@wlabarron Awesome, Thanks for confirming. Will therefore close.
