Modula plugin review and common issues

Custom Grid layout relies on CSS grid calculations based on the gallery container width. Layout breaks usually occur when: (1) the gallery container width on the frontend differs from the preview — check if a page builder section is adding padding or margin that reduces the available width; (2) a conflicting CSS rule from the theme or another plugin overrides Modula’s grid styles — use browser DevTools to inspect the gallery container’s actual computed width; (3) the gallery is embedded inside a very narrow column — Modula’s custom grid needs sufficient width to render correctly. Set a minimum width for the gallery container via custom CSS if needed.

Gallery filtering requires the Modula Filters extension (Pro feature). If you have Pro: (1) verify images have tags assigned — in the gallery editor, click each image and add tags in the Tag field; (2) enable the filter bar in Gallery Settings → Extensions → Filters; (3) check browser DevTools Console for JavaScript errors that prevent filter click handlers from attaching; (4) clear all caches — cached pages may serve the gallery without the filter interaction scripts properly loaded. Also verify the filter extension is activated in Modula → Extensions.

Caption mismatches indicate a caching or image order issue. In the Modula gallery editor, each image has its own Caption, Alt Text, and Title fields — verify the correct caption is assigned to each image in the editor. After making changes, clear all page caches. If captions are still wrong, check if images were bulk-uploaded and assigned captions from the WordPress media library attachment descriptions — Modula pulls caption data from the attachment record if individual image captions are not set. Set captions explicitly in the Modula image editor for each gallery item.

With Modula Pro and the Filters extension: (1) upload images to your gallery; (2) click each image in the gallery editor and add tags (e.g., “branding,” “web design,” “photography”) — multiple tags per image are supported; (3) in Gallery Settings → Extensions → Filters, enable the filter bar and configure its position and style; (4) optionally set a default active filter. Publish the gallery. Visitors see filter tabs above the gallery that filter images by tag with a smooth AJAX transition animation.

Password protection requires the Modula Password Protection extension (included in Starter plan and above). In the gallery settings, go to Extensions → Password Protection. Enable password protection and set the password for the gallery. When visitors access the gallery shortcode page, they see a password entry form before the gallery is displayed. The password is stored per-gallery — different galleries can have different passwords, allowing you to create separate protected galleries for different clients.

Modula’s custom drag-to-resize grid is particularly valuable for creative agencies that want distinctive, art-directed layouts that stand out from standard masonry grids. If the gallery’s visual uniqueness is a priority, Modula gives more creative control. Envira Gallery is faster-loading and simpler to manage, which is advantageous for agencies handling multiple client sites efficiently. For a single showcase portfolio where visual distinctiveness matters, Modula. For managing galleries across many client sites with consistent performance, Envira.

Yes — Modula Pro’s Video extension adds support for YouTube and Vimeo video thumbnails displayed in the gallery grid, opening in a lightbox video player when clicked. Videos appear alongside images in the same gallery with appropriate play button overlays on thumbnails. Self-hosted video files are also supported via direct URL. Video support is available in the Creator plan and above.

Yes, that can happen, especially on older sites with many plugins. This usually happens when the plugin, theme, and add-ons are updated out of sequence. In most cases, testing on staging catches the issue before it reaches the live site. From experience, backups and changelog reviews save a lot of cleanup time.

Start by checking whether another plugin already does the same job. In most cases, overlap is what creates avoidable conflicts and performance issues. A common issue is installing a plugin because it looks convenient without checking the stack first. From experience, a short compatibility review avoids most of the pain later.
