Custom Icon Font Files Missing On Disk Despite Active Icon Entries — Breaks Dynamic Filter Widget
B
belex24
Hi there! We have a "Dynamic Filter" widget that uses several Custom Icons. These are listed as active in the Custom Icons screen, but the generated font/CSS files under media/com_sppagebuilder/assets/iconfont/{hash}/ are missing entirely from disk — in both production and staging. Only an empty placeholder folder exists.
Affected hashes: Codexsppb9b929c4f, Codexsppbf44d4e94, Codexsppb18b0f455, Codexsppb9dd871fd, Codexsppba181f4f6, Codexsppbc325fdc6, Codexsppb6b642e9f, Codexsppbd5c6e7d5, Codexsppb4b4581cd, Codexsppb24bd4c06, Codexsppbb6fe8c6a, Codexsppb26877bda, Codexsppba2831d55
Steps to reproduce: Toggle a Custom Icon off/on → no effect, no file regeneration. FTP check confirms the iconfont/ subfolders don't exist. Loading the front-end page with the filter results in a 404 on the CSS file.
Impact: On production (behind Sucuri, which sends X-Content-Type-Options: nosniff), the 404 is returned as text/html and hard-blocked by the browser as a stylesheet → the search widget fails to initialize, with no JS error in the console. On staging (plain Apache, no nosniff, 303 redirect instead of 404), the browser is more lenient and the issue stays hidden — even though the same files are missing there too.
Questions for support:
Why would Custom Icons stay "active" while their generated assets are missing from disk? Known issue after migration/DB import? Is there a way to force-regenerate the physical files for existing entries without re-uploading the original icon package? If not, does re-uploading via "Upload Icon" preserve existing icon references in the Dynamic Filter, or do they need manual reassignment afterward? Attachments: Custom Icons overview screenshot, browser console MIME error screenshot, FTP screenshot of the empty folder.

Accepted AnswerHello,
First, please delete all of these Custom Icon entries from the database, as the corresponding icon files have already been removed from the iconfont folder. Since the database still contains references to them, the missing generated assets are causing the 404 errors.
Regarding reassignment, if you still have the original icon ZIP files, simply upload them again. There is no need to manually reassign the icons, provided they are uploaded with the same configuration.
If you no longer have the original ZIP files, you can recreate the custom icons. Just make sure to use the same icon prefix as before. This will allow your existing icon references to continue working without requiring manual reassignment.
Thanks!
