# Common Errors
> Troubleshooting common issues with Skelementor
## Import Errors
### "reserved\_class\_name" Error
**Cause:** You're using a reserved name like `container`
**Solution:** Use a different name like `.cont`, `.wrapper`, `.site-container`
```css theme={null}
/* Instead of */
.container {
max-width: 1200px;
}
/* Use */
.cont {
max-width: 1200px;
}
.wrapper {
max-width: 1200px;
}
.site-container {
max-width: 1200px;
}
```
### "invalid\_value" Error
**Cause:** Missing units on values that need them
**Solution:** Add `px`, `%`, `rem`, etc. to numeric values
```css theme={null}
/* Instead of */
.text-large {
font-size: 24;
}
/* Use */
.text-large {
font-size: 24px;
}
```
### Duplicate Classes Error
**Cause:** Classes with same names already exist
**Solution:** Delete existing classes first, then re-import
Go to Elementor → Global Classes panel and delete the conflicting classes
Re-run the Skelementor Preset or import your reduced test sample again
## Classes Not Working
### Classes Import But Don't Work
**Possible Causes:**
* Property values use incorrect format
* Z-index classes need position:relative
* Elementor cache needs clearing
**Solutions:**
```css theme={null}
/* Check property values */
.items-center {
align-items: center;
} /* Correct */
.items-center {
align-items: flex-center;
} /* Incorrect */
/* Z-index classes automatically get position:relative */
.z-10 {
z-index: 10;
position: relative;
}
```
### Empty Variants in Global Classes
**Cause:** Property type not supported by parser
**Solution:** Check that CSS property is in the supported list
### `_elementor_global_classes` Looks Empty
**Cause:** On Elementor **4.1**, that key may stay empty even when the import succeeded
**Solution:** Check Elementor’s Global Classes UI, `e_global_class` posts, and the kit metadata keys that track labels, order, and class-to-post mappings
## Troubleshooting Steps
### Step 1: Delete Specific Classes
Delete the specific failing classes in Elementor's Global Classes panel
### Step 2: Import in Smaller Batches
Import 20-30 classes at a time to avoid timeouts
### Step 3: Check CSS Syntax
Look for missing semicolons, units, etc.
### Step 4: Clear Elementor Cache
Go to **Elementor → Tools → Regenerate CSS**
### Step 5: Nuclear Reset
If all else fails:
Go to Elementor → Global Classes panel and delete everything
Remove any global CSS variables if they exist
Import your CSS fresh through Skelementor
## Performance Issues
### Slow Import Process
**Solutions:**
* Start with the built-in Skelementor Preset before debugging custom samples
* Import reduced samples in smaller batches when isolating failures
* Check server PHP memory limit
* Ensure stable internet connection
### Classes Not Applying
**Solutions:**
* Clear browser cache
* Clear Elementor cache
* Check for CSS conflicts
* Verify Elementor **v4** and Atomic Editor compatibility
