[mapguide-users] Base maps disappear and can not be displayed after using Theme Widget

Wed Nov 2 12:13:29 PDT 2022

Hi,

I am using Mapguide V3.1.2 and mapguide mastero 6.0m11. When I use the
Theme in fusion, a new layer is created and is shown in the Legend and I
see the map with the new colors. But the issue is that the base map doesn't
display and returns pink images. And even won't be displayed by switching
the base maps icon. Do you know what is the problem?
Looking at the errors in Console, it looks like the error is related to
/mapguide/fusion/widgets/Theme/themecontroller.php
and it says" XML Parsing Error: not well-formed Location: /
mapguide/fusion/widgets/Theme/themecontroller.php
<http:///mapguide/fusion/widgets/Theme/themecontroller.php> Line Number 1,
Column 1:"

and from there looking at the web developer tool, I see the following error

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html

2%;position:relative;}.content-container{background:#FFF;width:96%;margin-top:8px;padding:10px;position:relative;}--></style></head><body><div
id="header"><h1>Server Error</h1></div><div id="content"> <div
class="content-container"><fieldset>  <h2>500 - Internal server
error.</h2>  <h3>There is a problem with the resource you are looking
for, and it cannot be displayed.</h3>
</fieldset></div></div></body></html>

I can not find this code in themecontroller.php.

Please let me know how I can fix this

Hadis
