Hi,
I recently purchased Site Drive and just started to explore it.
I have a few questions so far.
Hey @referee,
I tested in my setup and it works but maybe the setup is different so please provide the login credentials to your site in a Secure Note and we’ll check the ACF setup.
We’re not sure what you mean. Can you provide screenshots?
Thanks.
Hey @christian,
I have added credentials to the Security Note of my original request.
Under the second point, I am referring to posts that have been added to the created CPT. I see that Site Drive moves ACF CTP, its Taxonomies and Field Groups but not the posts which have been added at the source site to the respective CPT. Documents posted in my example.
Hello John,
To add the “Athlete” custom post type, go to SiteDrive > Settings > Integrations > Posts > Manage and add the CTP.
Once added, you should be able to add CPT items in your drive.
Hope this helps.
Cool, thanks @ruenel .
So the terms for taxonomies and CPT posts should be added first as the types for import in the settings. The only issue I still have is the nested fields within repeaters. They get lost somewhere during import.
And I forgot one more thing. What does this error mean and is there a way to fix it?
Additionally, I have a question regarding the import of PRO Settings. If I click Export inside Theme Options Manager it looks like it generates XCS file but I do not see where it is stored. Not to the downloads folder, at least. In Corner Stone, the settings import/export feature works smoothly.
Hey John,
Please stay tuned as we’re replicating the ACF repeater issue.
About the error, kindly provide details as to what you’re sharing in Sitedrive. But, the common causes are below:
| Cause | Explanation |
|---|---|
| Corrupted base64 transfer | The base64 encoding/decoding between sites introduced corruption, producing an invalid zip |
| Incomplete transfer | PHP max_execution_time or memory limits cut the transfer short before the full zip was written |
| Source plugin missing its main file | The source plugin directory doesn’t have a valid plugin header file (e.g., the main .php file is missing or has no Plugin Name: header) |
| Empty or broken zip created |
sitedrive_base64_zip_create() failed silently (e.g., source directory unreadable), producing an empty/invalid zip |
| Server PHP memory limit | A very large plugin zip exceeds WP_MEMORY_LIMIT , causing the zip to be incomplete when written to disk |
| Temp directory permission issue | The temp file was written but improperly (partial write), resulting in a structurally invalid zip |
| Zip contains no root folder | If ZipArchive::getNameIndex(0) returns nothing or the zip structure is flat/unexpected, WordPress can’t locate the manifest |
The most likely culprit is a corrupted or truncated zip during the base64 transfer , often caused by PHP time/memory limits on either the source or destination server when syncing large plugins.
It’s in your browser’s downloads folder.
Hi again @christian,
I am sharing only the ACF CPT, taxonomies, and field groups. The issue occurs even if I add just one of the fields that have nested repeater fields and nothing else. I do not have any base64 content on the site.
max_execution_time is set to 300
WP_MEMORY_LIMIT is 480M
And here is the output in the log when I import Documents CPT its taxonomies and field groups:

The Warnings will be addressed when the patch update rolls out in the next few days.
As for your issue;
1.) You only shared the ACF field groups, taxonomies, and CPTs. You have not shared the actual CPT items that use these ACF elements. When we create a new document, the taxonomies are already present:
The Document CPT items were not because they have not been shared as shown here:
2.) The XCS File may have been downloaded to your computer. Check yout your downloads folder. If you can’t find it, it is best to set your browser’s downloads folder option to “Always ask me if I want to save a file or open it without saving”.
Best Regards.
Thanks @ruenel,
I understood that already in relation to moving the terms of the taxonomies and CPT posts (both should be added separately inside Posts Section and not ACF Section). The only challenge I currently face is dealing with nested fields inside repeaters. They still are not transferred even if I add all necessary sync types.
And after I did a wp search-replace for the taxonomy title doc-author (it was document-author before) on the source site, those terms are not synced or transferred anymore. Probably I need to fix something else at the source site database before SiteDrive sees them again.
This is great that the Warnings are under the radar for the fix.
Thank you for this info. This is probably the cause of the issue. If you can bring the old taxonomy name back and test Sitedrive again, that would be great.
@christian,
If I execute a backward wp search-replace command, everything returns back to normal, and SiteDrive can synchronize the respective taxonomy terms. However, nested fields within repeaters are still missing.
Thanks for the update. This needs deeper investigation. Please stay tuned.
