I was going through converting my alert templates through the web UI. All but one converted. When I attempt to update the template after clicking the convert button, I receive the message “An error occurred updating this alert template.”
When I watch the librenms.log file as I update the template, I see the following:
[2018-10-19 16:34:07] production.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Parse error: syntax error, unexpected 'else' (T_ELSE) in /opt/librenms/storage/framework/views/a2be9d57b26e239a2622ac2b3dcc95d8:10

Here’s the template code before the conversion:
{if %transport == slack}
%title
**NMS Status Page:** https://nms.bdg.link/device/device=%hostname
**Device Page:** https://%hostname/
{foreach %faults}
**Alerting Interface:** %value.ifDescr
**Current Speed:** %value.ifHighSpeed {if %value.ifHighSpeed == 1000}Gbps{else}Mbps{/if}
{/foreach}
{else}
%title
NMS Status Page: https://nms.bdg.link/device/device=%hostname
Device Page: https://%hostname/
{foreach %faults}
Alerting Interface: %value.ifDescr
Current Speed: %value.ifHighSpeed {if %value.ifHighSpeed == 1000}Gbps{else}Mbps{/if}
{/foreach}
{/if}
Here’s the same code after conversion:
@if ($alert->transport == slack)
{{ $alert->title }}
**NMS Status Page:** https://nms.bdg.link/device/device={{ $alert->hostname }}
**Device Page:** https://{{ $alert->hostname }}/
@foreach ($alert->faults as $key => $value)
**Alerting Interface:** {{ $value['ifDescr'] }}
**Current Speed:** {{ $value['ifHighSpeed'] }} {if {{ $value['ifHighSpeed'] }} == 1000}Gbps @else Mbps @endif
@endforeach
@else
{{ $alert->title }}
NMS Status Page: https://nms.bdg.link/device/device={{ $alert->hostname }}
Device Page: https://{{ $alert->hostname }}/
@foreach ($alert->faults as $key => $value)
Alerting Interface: {{ $value['ifDescr'] }}
Current Speed: {{ $value['ifHighSpeed'] }} {if {{ $value['ifHighSpeed'] }} == 1000}Gbps @else Mbps @endif
@endforeach
@endif
