Hi, I've been getting an error when trying to save a new page I've just created within an existing wiki.

wanderers-sandbox.wikidot.com
The ajax request failed. Please check your internet connection or
report a bug if the error repeats during your work.
code:502

When trying to do some edits on the page http://wiki.glidernet.org/list-of-receivers-dutch, I need to login on http://wiki.glidernet.org/list-of-receivers-dutch.
When I do so, using my valid wikidot username and password I end up on a page with url http://ognproject.wikidot.com/afterlogin.php.
That page hangs indefinitly with the text "Please wait…".
I draw the conclusion that my login credentials are correct, because if I change one character in username or pw, the result is "The login and password do not match".

My English is terrible, so most of the English content in this feedback was translated from Chinese to English using Google Translate

English（Google Translate）：
If the email is linked, garbled characters will appear in Chinese:
for example:
moc.elpmaxe|troppus#��ﶻ䮂鑏呈晻�
Actually the source code is like this:

[support@example.com 给我发邮件！

中文：
如果链接邮箱，使用中文会出现乱码：
比如：
moc.elpmaxe|troppus#��ﶻ䮂鑏呈晻�
实际上源代码是这样的：

[support@example.com 给我发邮件！]

Installation fails because installer places temp files on wrong folder.
The installer places files on `C:\Users\TheGamerX\AppData\Local\Temp\QTTabBar`.
But the modified environment variable points to `Y:/temp`.

When I view ttrak.wikidot.com on my iPhone, the “Recent Changes” tab does not display. If I use a different phone or a computer, the tab is available to see recent changes to the site.

When I tried to save, a browser pop-up told me
"""
The ajax request failed.Please check your internet connection or report a bug if the error repeats during your work.
code:500
"""
and then I found that the save failed. (however, the draft can be saved successfully.)
I tried to change the browser, change to the mobile phone for editing, and even reset the network, but still can't save.
But when I delete part of the code, it can be saved normally.
Here is the part of the code.

Search is temporarily unavailable, we are working to bring it online!

Its been on all sites, why?
