The IBM Content Template Catalog V3.0 (CTC3) can be installed on IBM Web Content Manager (WCM) V18.104.22.168 or 22.214.171.124. Installing the Combined Cumulative Fix 009 or 010, or upgrading to fix pack level 126.96.36.199 renders CTC3 unusable.
A fix will be made available in the near future and this page will be updated when more information is available.
The IBM Content Template Catalog V3.0 (CTC3) is documented here: -
One of the files necessary for its successful operation is overwritten when installing either Combined CF009, CF010, or fix pack 188.8.131.52. The .jar file, "wp.wcm.templating.jar", is installed into the WCM shared apps directory during a CTC3 install.
To correct the issue, copy the original .jar file from CTC3 back into the shared apps directory (replacing the file present) and restart the server.
The .jar file is located in "/wp.ctc/components/wp.ctc/enablment/" in the CTC PAA. The non-CTC3 file will be 31KB after installing the CF or fix pack but the CTC3 version is 80KB.
After the restart, the templating functions should be working again.
