The questions that come up most often, and their short answer.
A block, a row or an element does not appear on the site
Look at the What will be output panel: it applies the same rules as the page. The usual causes:
- the eye is crossed out on the block, the element or the card;
- the block points to a row that does not exist (number rule, chapter 4);
- the row has no block;
- the element is empty: a button without a label, a tab or a panel without a title, a link without a label are not output.
I moved a row and my blocks changed place
That is the number rule: blocks point to their row by its position. Move the row back to its original place, then change the row number of the blocks concerned.
I chose a layout and everything was replaced
Choosing a layout replaces the current layout, after confirmation. If you confirmed by mistake, close the module without saving: nothing is lost until you save. To add a section, use the + of the block list.
My text is cut off after saving
The module has reached the 64 KB limit of a Joomla settings field. Look at the gauge in the Custom CSS tab, shorten your texts, or split the layout into two modules.
Also check that the System - Opus plugin is enabled. With it, Opus sends the whole layout in a single field; without it, a very large page can go over PHP's limit on the number of fields sent (max_input_vars), and the end is lost.
The module takes a long time to open
Check that the System - Opus plugin is enabled, and that its Light form setting is on Yes (chapter 1). Even a large page then opens in a second or two.
The site search does not find the text of my blocks
The System - Opus plugin lets Joomla's Smart Search read the text of Opus modules placed in an article. After updating Opus, run the indexing once: Components → Smart Search → Index.
My colours do not apply
Opus only sets classes, which the template dresses. Check that your rule is prefixed with the module's class, and that it does not target a shared class instead of one of yours (chapter 7). Do not use !important.
My icon shows as a solid square, or not at all
Solid square: the file has no transparent background (a JPEG, or a PNG on a white background). Nothing at all: the SVG has no viewBox, or its shapes only exist through their outline (chapter 7.1).
Do I need Corpus?
No. Opus works under Cassiopeia and under any Bootstrap template. Under Corpus, it borrows its design directly and adds no script (chapter 8.1).
Can I put several Opus modules on the same page?
Yes, and that is the intended way to build a page: one module per section, each in its own position, with its own menu assignments.
Support
By email or through the contact form on joomanji.eu, on working days. Give the version number, shown in the Module tab, and the template you use.
