Solution for “modules was requested to be downloaded in different versions (x.x and y.y)”
If, when installing extensions in TYPO3, the message appears that "modules" was requested to be downloaded in different versions (e.g. "x.x and y.y"), the cause is often outdated/stale data in the extension list from the TYPO3 Extension Manager.
Quick fix
Empty the table tx_extensionmanager_domain_model_extension in your TYPO3 database and try again. The table will be repopulated automatically with up‑to‑date data on the next fetch.
Steps
- Using SQL (via phpMyAdmin/Adminer/CLI), run:
TRUNCATE TABLE tx_extensionmanager_domain_model_extension;- Alternatively, use your DB tool’s “delete all rows” on that table (do not drop the table!).
Afterwards, reload the Extension Manager (extension list) or repeat your action.
