Accessibility

@Frank, we hope the version just released fixes the issue, but TBH we are having a hard time reliably replicating the problem. Hopefully fixed, but maybe we will need to revisit this again.
If you (or anyone else) knows how to replicate it, please add a comment here https://github.com/ponlawat-w/moodle-local_accessibility/issues/30

We are using the accessibility plugin since August 2025, and our support center complains about quite many calls of users who cannot control Moodle anymore due to black screens. Unfortunately, we haven't yet been able to reproduce, how those users manage to get into the black screen issue. Is tere any remedy to avoid this situation?

@Gustavo, we hope the version just released fixes the issue, but TBH we are having a hard time reliably replicating the problem. Hopefully fixed, but maybe we will need to revisit this again.
>> Could you add a widget with predefined accessible color combinations (background + text)? Choosing colors separately can result in unreadable combinations, like black text on a black background. Is this possible?
This is, of course possible (other plugins have taken this approach), but it's not on the current road map. This plugin is about freedom. If the user wants (for whatever reason) black text on black backgrounds, then they should be free to do so. Rather than prevent impossible to see combinations, we're more looking for a way to ensure that the reset button be forced to have contrast and visibility. As for preset palettes, we would invite you Mr. "Web Developer" to build a widget for that. Instructions for building your own widget can be found on the Github page. We'd love to incorporate other widgets, so don't hold back.

Thanks for this great tool! Could you add a widget with predefined accessible color combinations (background + text)? Choosing colors separately can result in unreadable combinations, like black text on a black background. Is this possible?

Hello @Adam
We are facing the same issue as @Monica and @David
We tried to apply the fix mentioned in https://github.com/ponlawat-w/moodle-local_accessibility/issues/30 but it didnt solve the problem.
Do you have any prediction on the new version?

@Damien, I just had a quick look, and as you note, H5P is not affected by the settings in this plugin. We did have to add a style to prevent the accessibility button also being rendered in iframes, but I don't think this plugin has much control otherwise over how H5P and other iframe contents are rendered. Definitely something to look into though. Cheers.

Apologies for the late response. New academic year here so have been trying(failing) to keep up with everything.
Answers:
@Fran, When I get some time, I will try the Lambda theme and see what the issue is there. Until then perhaps you could contact the Lambda creators and see if they have any ideas?
@Justin, yes, black text on a black background is possible to set. I've been trying to think of a way to solve this while at the same time maintaining the freedom of choice. Not sure what you mean about the images though.
@Al, For screen-reader capabilities, we would love for someone like Readspeaker to offer to make a widget that we could include. Otherwise, we're looking towards having the plugin connect to whatever TTS solution the user's browser/OS is using. Yes, we definitely want to add TTS to this soon.
@Monica and @David, I have just started noticing this happening myself. Thanks for adding this issue to the Github David, we will work on getting it fixed soon.
@Ezzeddin, The goal of the plugin is to put as much control as possible in the hands of the users, not so much the admins. That said, as it grows more complex, a settings page will soon become necessary I expect. Re: the login page question, if you could perhaps make an issue on Github https://github.com/ponlawat-w/moodle-local_accessibility/issues preferably with screenshots, that might help us understand the issue. From your description, it sounds like some CSS for the login page is interfering with the panel display. Perhaps a tweak to your theme's CSS might fix the issue.
Thank you all, and I'll try to respond sooner in future.
Cheers

Hi and thanks for the plugin ! I have installed it and it works great but not for the content in iframe like H5p or SCORM. Do you have a solution for this ? Greetings.

Hello,
A nice plugin.
I also add the need to make it controllable in terms of colors and availability of every feature. I think it will need a settings page to control every thing.
In the login page, when I use a narrow login popup/area accessibility shows as a narrow popup which does not look nice. In this case, it should be wider.

Hi @Monica Bokos...
It's happened to us a couple of times too. It seems to be with some keys but we have not been able to detect when it happens.

Hello, Some of our users are writing us that their background turned black all of a sudden. We are in Moodle 4.1 and I can't have any more info. It works fine for most of us, did anybody else encounter this issue ? Thanks

What a fantastic plugin, so useful. Allowing student to pick their own colours is amazing as different shades make the difference. Much better than preset. Do you have plans to have the page read out?

An issue is that it does make some items in Moodle inaccessible - such as certain buttons with a dark background (it doesn't seem to change those effectively - same with some images that might be in contrast to the native layout, no longer works with this widget)

Hi, thanks for this fantastic theme.
It works perfectly with several design themes
Except one in particular: Lambda. https://themeforest.net/item/lambda-responsive-moodle-theme/9442816?ref=eva_pi
I've tried different CSS settings (z-index, etc.) and I can't get it to be the button visible. What else can I do?
I'm running moodle 4.0

Great plugin, thanks.
