Hello,
a lot of questions in these forums are related to:
After installing JoomSEF, there are SQL queries visible over my page, why is that?
or other problems, that have however the same cause - previous installation of sh404sef.
Please make sure that
if you had sh404sef installed previously in your Joomla site, that after uninstalling it, also
all its DB tables were removed successfully, especially the
jos_redirection table.
These components - JoomSEF and sh404sef use the table with the same name, however, there are not fully compatible, so JoomSEF cannot write to
jos_redirection table created by sh404sef and that leads to many error, often hiddeous ones.
Also
note that sh404sef does NOT clean its table on uninstall by default, so you will most probably to do this manually.
The process to follow is:
- Uninstall JoomSEF (if already installed)
- Check your database using a DB tool such as phpMyAdmin and check if table jos_redirection exists. Please, note that other table prefix than jos_ may be used, this depends on your DB + Joomla configuration. If it exists, delete it. If other sh404sef tables also exist, you may delete them as well, but the other tables are not conflicting with JoomSEF, so it does not matter if thet stay in your DB.
- Reinstall JoomSEF
