Most Common Issues Found
🔴
Flair element hidden by inline style
The most widespread conflict detected — appears in every critically-scored store. A third-party app injects a flair element and then immediately hides it via display:none inline style. Prevents legitimate theme features from rendering correctly.
Critical · Present in all 0/100 stores
🟡
Third-party app CSS override conflicts
Multiple apps injecting competing stylesheets with high-specificity selectors. Causes unpredictable visual regressions across theme updates.
Warning · Common across moderate-score stores
🔵
App script loading order conflicts
Review apps and marketing tools loading before the theme's core scripts, causing initialization race conditions on product pages.
