Warning Icon - start - Icon (). Error while rendering: We can't get the icon path. Error: The icon (mdi:vector-combine) could not be downloaded.

[cctv18]

Environment: Windows 10 Professional + Apache 2.4.39 + PHP 7.4.5, installed necessary php extensions (pdo_sqlite, mbstring, openssl, intl & gd2) and newest dokuwiki sqlite plugin, having set upload_max_filesize and post_max_size to 300M
Just when I installed Combo plugin and activated it, all content pages started to display abnormally, with a line of red text like this:

Icon (). Error while rendering: We can't get the icon path. Error: The icon (mdi:vector-combine) could not be downloaded. Error: (We couldn't find the icon vector-combine) from the library mdi. Error: fopen(): php_network_getaddresses: getaddrinfo failed: ����������Ч�������Ҳ����������͵���ݡ� .. (ie media or icon name attribute is mandatory).

and when I disable Combo plugin, everything returns to normal. Here's the log messages in the console tool of Edge:

combo.min.js:1 Uncaught SyntaxError: Unexpected token '<'
cache.js:1 Uncaught SyntaxError: Unexpected token '<'

and the error log of Dokuwiki:

Meanwhile, I noticed the error information in the console tool of Edge, which the path of JS files was shown like this:
http://127.0.0.1/_media/library/combo/combo.min.js?drive=combo&fetcher=raw&tseed=1717952350
http://127.0.0.1/_media/snippet/js/cache.js?drive=combo&fetcher=raw&tseed=1717952350
http://127.0.0.1/_media/snippet/js/metadata.js?drive=combo&fetcher=raw&tseed=1717952350
http://127.0.0.1/_media/snippet/js/combo-search-box.js?drive=combo&fetcher=raw&tseed=1717952350

however, there's not a single directory named "_media" under the root directory of my website. Is it a problem caused by path reference, a bug or anything else?

Hy cctv18!

Sorry for that. Man.

vector-combine
vector-combine is the logo of combostrap.
Combostrap downloads the icons the first time when it does not find them. The error gives even the [url](https://raw.githubusercontent.com/Templarian/MaterialDesign/master/svg/vector-combine.svg)

The error in php is here:

Error: fopen(): php_network_getaddresses: getaddrinfo failed

Php uses the getaddrinfo to detect the IP server from the server raw.githubusercontent.com . And it couldn't.
This is a DNS problem.

_media
You get the _media path because the rewrite is configured but it seems that the rewrite is not. In Apache, you need a htaccess, on nginx, you need another one.
See here for all configuration by web server.

This errors:

http://127.0.0.1/_media/snippet/js/cache.js?drive=combo&fetcher=raw&tseed=1717952350

are because you get not a javascript but a HTML error page I presume.
You should copy the URL into the browser to see them.

[gerardnico]

I created a test page without any rewrite.
And it works for me on our demo.

[cctv18]

Thank you!
I tried to set jquerycdn to use code.jquery.com as CDN in dokuwiki's configuration setting, turn off URL rewrite and refresh the page, and the page seemed to be normal. Then I turned on URL rewrite again, there was still no error in the console tool of Edge.
However, when I tried to click the function buttons, the buttons were not corresponding, and there were errors appearing in the console of Edge:

and when I refresh the page again, the index bar and some of the font display in the page appeared to be abnormal:

Meanwhile, when I tried to open another page, a large number of warning/error prompts appeared on the page:

I really have no way to solve the problems above. Is this because of some runtime environment missing or some plugin conflict?

[gerardnico]

The error is here

TypeError: Cannot read properties of undefined (reading 'Modal')

combo.min.js is a wrapper around bootstrap js to create modals.

It means that bootstrap JavaScript was not loaded.

Combostrap is already on cdn since a couple of years long before dokuwiki implemented it.
It has no impact with Combostrap because it does not use this configuration.

As specified here:
https://combostrap.com/performance/strap-cdn-m55ukl58

For the warnings, Combostrap detects every xml tag in a page for performance reason.

https://combostrap.com/docs/combostrap-styling-marki-language-31meei51

If you want br, p tag to be printed you need to escape them with 2 percentage characters before and after them.
